1240742 玖、發明說明： 【發明所屬之技術領域】 本發明係有關一種適合於丙烯酸溶膠的丙烯酸系聚合 體粉末、含有該丙烯酸系聚合物粉末及可塑劑之丙烯酸溶 膠、及由該丙烯酸溶膠所得的成形物。 【先前技術】 塑膠溶膠係爲使樹脂粉末及塡充劑分散於可塑劑之溶 膠狀態者，使該物進行塗覆等後加熱凝膠化形成成形品。 目前以該方法工業上廣泛使用的樹脂係爲聚氯化乙烯（氯乙 烯），稱爲氯乙烯溶膠或氯乙烯漿料。視用途而定該氯乙烯 組成物使用作爲汽車用、地毯用、壁紙用、床用等之塗覆 劑、含浸劑、塡縫劑等，在很多領域中以各種目的使用。 另外’由氯乙烯組成物所得的成形品於燃燒處理時因 聚氯化乙烯產生氯化氫氣體，會有燒卻爐顯著受損的缺點， 此外，最近爲環境問題、酸性雨原因、且地球臭氧層的破 壞原因物質，在各商品領域中企求沒有該缺點、可取代氯 乙烯溶膠組成物的塑膠溶膠組成物出現。 對該要求而言，提案使用丙烯酸系樹脂之丙烯酸溶膠 作爲燃燒時不會產生氯化氫氣體之塑膠溶膠。例如使用均 勻組成系丙烯酸聚合物粒子（參照日本特開昭5 1 -7 1 344號 公報或對應於此之〇81516510人（特別是申請專利範圍））， 使用一辛基駄酸酯之一般可塑劑時上述粒子對該可塑劑之 溶解性高、混合後在數分鐘內會引起丙烯酸溶膠之黏度上 升、無法成膜，會有實用上無法使用的問題。而且，爲提 一 6 - 1240742 高丙烯酸溶膠之成膜性及儲藏安定性時，提案使丙烯酸聚 合物中與可塑劑之相溶性低的單體成分共聚合方法（特開平 5_2 7 95 3 9號公報或對應於此之EP 5 3 3 0 2 6A(特別是參照申請 專利範圍）），使用該溶膠組成物時在所得皮膜表面上會有 可塑劑容易滲出的問題。 而且，已提案二次平均粒徑爲0.1〜500μπι之範圍，在 可塑劑中分散丙烯酸溶膠所得的塑膠溶膠組成物（特開昭 5 1 - 7 1 3 44號公報或對應於此之GB1 5 165 10Α(特別是申請專 利範圍）、特開昭5 4- 1 1 7 5 5 3號公報（特別是參照申請專利範 圍））°然而，使用二次平均粒徑微細的丙烯酸系聚合物之 丙烯酸溶膠時，由於丙烯酸系聚合物粒子之單位體積的粒 子面積大時初期黏度高，容易產生膨脹現象，流動性降低 且塗覆時塗覆膜之厚度不均勻或產生掠過情形，噴霧塗覆 時產生噴霧粉末不均勻等問題。爲使該含有二次平均粒徑 微細的丙烯酸系聚合物之丙烯酸溶膠爲實用黏度時，可塑 劑量變多’且必須添加稀釋用有機溶劑等。結果，此時在 皮膜表面上可塑劑會滲出且機械強度降低，添加的有機溶 劑殘留於塗膜中容易形成成膜性受損之問題。 另外’使用含有二次平均粒徑大的丙烯酸系聚合物之 丙燒酸溶膠時，其黏度會有較含有二次平均粒徑微細的丙 燃-酸系聚合物之丙烯酸溶膠爲低的傾向，丙烯酸溶膠中丙 烯酸系聚合物之均勻性不佳，會有成膜中產生顆粒、無法 形成平滑皮膜的問題，另外，皮膜因加熱凝膠化的時間必 須很長’故會有丙烯酸溶膠塗覆品之生產性降低的問題。 -7- 1240742 此外，提案有含丙烯酸聚合物粒子之平均粒徑爲〇. 1〜 2.0μηι者與3.0〜50μπι者之混合物的低黏度丙烯酸溶膠（特 開平8 -7 3 60 1號公報）（特別是參照申請專利範圍），惟會有 必須使乾燥的樹脂（二次粒子）藉由分級或粉碎達成企求的 粒度分布、混合的複雜工程，因與可塑劑混合時產生的切 變力致使粒子受到破壞，溶膠安定性降低的問題。 如上所述，在丙烯酸溶膠中使用二辛基酞酸酯之一般 可塑劑時，該可塑劑對上述粒子之溶解性高，混合後在數 分鐘內丙烯酸溶膠之黏度上升而無法成膜，會有無法實用 的問題。此外，爲提高丙烯酸溶膠組成物之儲藏安定性時， 使用在丙烯酸聚合物中與可塑劑之相溶性低的單體成分共 聚合的丙烯酸溶膠組成物時，所得皮膜表面上會有可塑劑 容易滲出的問題。如此使用丙烯酸聚合物粒子時，由於儲 藏安定性與成膜後之可塑劑保持性（耐滲出性）的關係相 反，無法滿足均勻構造的聚合物粒子。 因此，特開平 5 -2 795 3 9號公報或對應於此的 ΕΡ5 3 3 〇26 Α(特別是參照申請專利範圍）中提案使用芯核構造 粒子之丙烯酸溶膠組成物，使用在聚合物架構中含有酸之 丙烯酸系聚合物。然而，該公報中提案的聚合物對可塑劑 而言相溶性低’使用如酞酸酯系可塑劑之極性低的可塑劑 時，可塑化狀態不佳，無法製得良好的塗膜。另外，於特 開平6 - 3 2 2 2 2 5號公報或對應此之US 544 1 994A(特別是參照 申請專利範圍）中，提案使用相同芯核構造粒子之塑膠溶膠 組成物。此處，芯核構造粒子於製造均勻構造粒子且藉由 -8 - 1240742 使該物進行鹼加水分解處理，該粒子表面部分之酯基會變 換成羧基。然而，核部之厚度極薄，實質上粒子體積不會 超過1 %左右。作爲核部之效果所企求的儲藏安定性之改良 效果極低。另外，藉由鹼加水分解導入的核部，酸價極高， 對可塑劑之相溶性極低，使成膜性顯著降低。而且，該具 有高酸價核部之構造粒子在塑膠溶膠組成物中，粒子間容 易形成凝聚構造，結果塑膠溶膠組成物因切變速度而使黏 性提高，作業性降低。 而且，使用芯核構造之塑膠溶膠組成物的另一例於特 開平7-23 3299號公報（特別是參照申請專利範圍）及特開平 8 -2 95 8 5 0號公報（特別是參照申請專利範圍）中提案。此處， 基本上使用對可塑劑具相溶性之芯部與對可塑劑不具相溶 性之核部所成芯核聚合物時，可實現該基本性能（低水準儲 藏安定、低水準可塑劑保持性等）。然而，爲於工業上實用 化時，要求極高性能（高水準儲藏安定性、高水準可塑劑保 持性、高水準機械性能（拉伸強度、拉伸度等）等），藉由上 述公報提案的聚合物與可塑劑之相溶性平衡性無法最適 化，儲藏安定性、塗膜之可塑劑保持性及塗膜之柔軟性皆 爲低水準，不適於工業上實用化。 另外，於上述特開平8-295 85 0號公報（特別是參照申 請專利範圍）或特開平9-7 795 〇號公報（特別是參照申請專利 範圍）中提案，使用含有與可塑劑相溶性良好的特定單體所 成（a)成分、與可塑劑相溶性低的特定單體所成（b)成分，且 (a)成分之構成比例由丙烯酸系聚合物粒子之中心部朝最外 1240742 層多階段或連續減少，（b)成分之構成比例由丙烯酸系聚合 物粒子之中心部朝最外層多階段或連續增加的丙烯酸系聚 合物粒子之丙烯酸溶膠，由於所使用的丙烯酸系聚合物粒 子之形態或性質皆沒有明確規定，故粒子表面層與可塑劑 之相溶性低，可塑劑對二次粒子內之滲出性不佳，因成膜 中二次粒子殘留產生顆粒/無法形成平滑的皮膜，會有實 用上不爲企求的結果。 爲使該塑膠溶膠最基本的性質之儲藏安定性、可塑劑 保持性、塗膜柔軟性等並立時，進行各種檢討，由於所使 用的丙燒酸系聚合物等粒子之形態或性質沒有明確規定， 作爲氯乙烯之取代材料時皆爲低水準，故目前無法達到工 業上實用水準。 【發明之揭示】 本發明之目的係提供一種可形成儲藏安定性及流動性 優異的丙烯酸溶膠之丙嫌酸系聚合物粉末、具有使用該粉 末之上述特性的丙烯酸溶膠、以及由該丙烯酸溶膠所得的 成形物。 藉由發明之形態，本發明之目的係提供除上述特性外， 至少具有一種下述例舉特性之丙烯酸系聚合物粉末， (1) 可容易與可塑劑等混合。 (2) 可由該丙嫌酸系聚合物粉末形成低黏度丙烯酸溶 膠。 (3 )可由該丙燒酸系聚合物粉末形成流動性更爲提高的 丙烯酸溶膠。 1240742 (4) 可由該丙烯酸系聚合物粉末形成儲藏安定性更爲提 高的丙烯酸溶膠。 (5) 可由該丙烯酸系聚合物粉末形成耐粒子破壞性優異 的丙烯酸溶膠。 (6) 由該丙烯酸系聚合物粉末形成的丙烯酸溶膠所得的 成形物具有優異的可塑劑保持性或耐滲出性。 (7) 由該丙烯酸系聚合物粉末形成的丙烯酸溶膠所得的 成形物具有優異的皮膜均勻性。而且，由該丙烯酸系聚合 物粉末形成的丙烯酸溶膠可形成沒有顆粒的平滑塗膜。 (8 )由該丙烯酸系聚合物粉末形成的丙烯酸溶膠所得的 成形物具有優異的柔軟性。 (9)由該丙烯酸系聚合物粉末形成的丙烯酸溶膠所得的 發泡成形物具有優異的發泡狀態均勻性。 本發明之目的係提供一種具有使用上述各粉末之各種 特性的丙烯酸溶膠、及由該丙烯酸溶膠所得的成形物。 本發明之另一目的係提供一種使由該物形成的成形物 燒卻時與由氯乙烯溶膠形成的成形物不同，不會產生氯化 氫氣體之丙烯酸溶膠。 爲解決上述課題之本發明，由主要形態之形態1與另 外改良形態1之形態2、形態3、形態4及形態5所成。 形態1(空隙率）之特徵係爲使用具有特定構造特性之丙 烯酸系聚合物粉末。 換言之，形態1係有關使含有丙烯酸系聚合物粒子之 乳膠凝固乾燥所得的丙烯酸系聚合物粉末（二次粒子）中， -11- 1240742 該粉末之平均粒徑爲5〜1 ο ο μηι，空隙率爲7 0 %以下，且孔 直彳空Ιμτη以上之積分空隙體積爲〇.9mL/g以下之丙烯酸系 聚合物粉末。 該丙稀酸系聚合物粉末以粗孔直徑爲7μιη以下，且微 孔直徑爲0.5 μ m以下較佳。 而且’每1克該丙烯酸系聚合物粉末之粗孔細孔體積 A與微孔細孔體積B之比例（a / B )以0.5〜5較佳。 形態1之丙烯酸系聚合物粉末可形成儲藏安定性及流 動性優異的丙烯酸溶膠。 开> 悲2 (粒徑比）之特徵係爲使形態1之丙燒酸系聚合物 粉末之長徑與短徑的粒徑比設定於特定範圍內。 換言之’形態2係有關以電子顯微鏡觀察的該丙烯酸 系聚合物粉末之長徑a與短徑b之粒徑比a/b爲1 . 〇〜2之 丙烯酸系聚合物粉末。 形態2之丙烯酸系聚合物粉末係除形態〗之特性外， 另具有低黏度、優異流動性及儲藏安定性優異、且由該物 所得的成形物之可塑劑保持性優異的丙烯酸溶膠。 形態3 (水溶性高分子）之特徵係爲使用含有作爲形態i 或形態2之乳膠的丙烯酸系聚合物粒子及含有特定分子量 之水溶性高分子乳膠。 換言之’形態3係有關該乳膠含有丙烯酸系聚合物粒 子及重量平均分子量爲10,000以上之水溶性高分子的乳膠 中，使該水溶性高分子之使用量相對於1 〇〇質量份丙烯酸 系聚合物粒子而言爲0.001〜1 0質量份之乳膠噴霧乾燥， 1240742 製得的形態1或形態2之丙烯酸系聚合物粉末。 形態3之丙烯酸系聚合物粉末係除上述形態1或形態 2之特性外’另具有與可塑劑容易混合、低黏度、流動性、 儲藏安定性及耐粒子破壞性優異、且由該物所得的成形物 具有優異的耐滲出性及皮膜均勻性優異的丙烯酸溶膠。 於形態1〜3之任一形態中，丙烯酸系聚合物粒子以下 述規定的丙烯酸系聚合物粒子（I)或丙烯酸系聚合物粒子（n) 較佳。 丙烯酸系聚合物粒子（I): 係爲在含有前階段聚合物（I-a)之乳膠中形成後階段聚 合物（I-b)所得的多階段聚合物粒子， BU階段聚合物（I -

Shaped article. [Prior art] Plastisol is a resin powder and a filler dispersed in a plasticized state. The plastisol is coated, etc., and then gelled to form a molded article. At present, the resin widely used in the industry by this method is polyvinyl chloride (chloroethylene), which is called vinyl chloride sol or vinyl chloride slurry. Depending on the application, the vinyl chloride composition is used as a coating agent, an impregnating agent, a quilting agent, and the like for automobiles, carpets, wallpapers, beds, and the like, and is used in various fields for various purposes. In addition, the molded product obtained from the vinyl chloride composition has the disadvantage of being significantly damaged by the burning furnace due to the generation of hydrogen chloride gas from polyvinyl chloride during the combustion treatment. In addition, it has recently been caused by environmental problems, acid rain, and global ozone Substances of destruction cause plastisol compositions that do not have this disadvantage and can replace vinyl chloride sol compositions. For this requirement, it is proposed to use an acrylic sol of acrylic resin as a plastisol that does not generate hydrogen chloride gas during combustion. For example, use acrylic polymer particles of uniform composition (refer to Japanese Patent Application Laid-Open No. 5 1 -7 1 344 or 081516510 (corresponding to the scope of patent application)), and the general plasticity of an octyl gallate The above-mentioned particles have a high solubility in the plasticizer, and the viscosity of the acrylic sol rises within a few minutes after mixing, and the film cannot be formed, which causes problems in practical use. In addition, in order to improve the film-forming properties and storage stability of 6-1240742 high acrylic sols, a method for copolymerizing monomer components having low compatibility with plasticizers in acrylic polymers has been proposed (Japanese Patent Laid-Open No. 5_2 7 95 3 9 The publication or corresponding EP 5 3 3 0 2 6A (especially refer to the scope of patent application), when using the sol composition, there is a problem that the plasticizer easily leaks out on the surface of the obtained film. Moreover, it has been proposed that the secondary average particle diameter is 0. In the range of 1 to 500 μm, a plastisol composition obtained by dispersing an acrylic sol in a plasticizer (Japanese Patent Application Laid-Open No. 5 1-7 1 3 44 or corresponding GB 1 5 165 10 Α (particularly patent application scope), special Kaizhao 5 4- 1 1 7 5 5 3 (especially refer to the scope of the patent application) ° However, when using an acrylic sol with an acrylic polymer having a fine secondary average particle size, the unit of acrylic polymer particles is When the volume of the particle area is large, the initial viscosity is high, it is easy to produce swelling, the fluidity is reduced, and the thickness of the coating film is uneven or skimming during coating, and the spray powder is uneven during spray coating. In order to make the acrylic sol containing a fine acrylic polymer having a secondary average particle diameter into practical viscosity, the plastic amount is increased 'and an organic solvent for dilution must be added. As a result, at this time, the plasticizer will ooze out on the surface of the film, and the mechanical strength will be reduced, and the added organic solvent will remain in the coating film, which is likely to cause the problem of impaired film formation. In addition, when using an acrylic sol containing an acrylic polymer having a large secondary average particle diameter, the viscosity tends to be lower than that of an acrylic sol containing a fine secondary average particle diameter of an acrylic-acid polymer. The uniformity of the acrylic polymer in the acrylic sol is not good, and there are problems that particles are formed during film formation and a smooth film cannot be formed. In addition, the film must be gelled for a long time due to heating. The problem of reduced productivity. -7- 1240742 In addition, it is proposed that the average particle diameter of the acrylic polymer-containing polymer particles is 0.  1 ~ 2. 0μηι and 3. Low viscosity acrylic sol (mixture of 0 to 50 μm) (Japanese Unexamined Patent Application Publication No. 8-7-760) (especially referring to the scope of patent application), but it is necessary to classify or pulverize the dried resin (secondary particles) To achieve the complex project of desired particle size distribution and mixing, due to the shear force generated when mixing with the plasticizer, the particles are destroyed and the stability of the sol is reduced. As mentioned above, when a general plasticizer of dioctyl phthalate is used in an acrylic sol, the plasticizer has high solubility to the above particles, and the viscosity of the acrylic sol rises within a few minutes after mixing, preventing film formation. Impractical question. In addition, in order to improve the storage stability of the acrylic sol composition, when an acrylic sol composition copolymerized with an acrylic polymer and a monomer component having low compatibility with the plasticizer is used, the plasticizer may easily leak out on the surface of the obtained film. The problem. When acrylic polymer particles are used in this way, the relationship between storage stability and plasticizer retention (bleed-out resistance) after film formation is inverse, and polymer particles with a uniform structure cannot be satisfied. Therefore, in Japanese Patent Application Laid-Open No. 5-2795795 or corresponding EP5 3 3 〇26 A (especially referring to the scope of patent application), an acrylic sol composition using core structure particles is proposed for use in polymer architecture. Acrylic polymer containing acid. However, the polymer proposed in this publication has low compatibility with plasticizers. When a plasticizer with a low polarity such as a phthalate-based plasticizer is used, the plasticization state is not good, and a good coating film cannot be obtained. In addition, in Japanese Patent Application Laid-Open No. 6-3 2 2 2 2 5 or US 544 1 994A corresponding thereto (especially referring to the scope of patent application), a plastisol composition using particles having the same core structure has been proposed. Here, the core structure particles are used to produce uniform structure particles, and the substance is subjected to alkali hydrolysis treatment by -8-1240742. The ester group on the surface of the particles is converted into carboxyl groups. However, the thickness of the core is extremely thin, and the particle volume does not exceed about 1%. The improvement effect of the stability of storage as the effect of the nuclear department is extremely low. In addition, the core portion introduced by the hydrolysis of the alkali has an extremely high acid value, has extremely low compatibility with plasticizers, and significantly reduces film-forming properties. In addition, the structural particles having a high acid value core portion are easily formed into a coacervate structure among the plastisol composition. As a result, the plastisol composition has increased viscosity due to shear rate and reduced workability. In addition, another example of a plastisol composition using a core structure is disclosed in Japanese Patent Application Laid-Open No. 7-23 3299 (especially referring to the scope of patent application) and Japanese Patent Application Laid-Open No. 8-2 95 8 50 (especially referring to the scope of patent application) ). Here, the basic properties (low-level storage stability, low-level plasticizer retention) can be achieved when a core polymer formed from a core that is compatible with the plasticizer and a core that is not compatible with the plasticizer is basically used. Wait). However, for industrial practical use, extremely high performance (high-level storage stability, high-level plasticizer retention, high-level mechanical properties (tensile strength, elongation, etc.), etc.) is required. The compatibility between the compatibility of the polymer and the plasticizer cannot be optimized. The storage stability, the plasticizer retention of the coating film, and the softness of the coating film are low, which is not suitable for industrial practical use. In addition, it is proposed in Japanese Patent Application Laid-Open No. 8-295 85 0 (especially referring to the scope of patent application) or Japanese Patent Laying-Open No. 9-7 795 0 (especially referring to the scope of patent application) to use materials that contain good compatibility with plasticizers. (A) component made of specific monomers, (b) component made of specific monomers with low compatibility with plasticizer, and the composition ratio of (a) component is from the center portion of the acrylic polymer particles toward the outermost 1240742 layers Multi-stage or continuous decrease, (b) The composition ratio of the acrylic polymer particles from the center of the acrylic polymer particles to the outermost layer is increased in stages or continuously. Because of the acrylic polymer particles used, There is no clear regulation on the form or nature, so the compatibility between the particle surface layer and the plasticizer is low, and the plasticizer has poor exudation in the secondary particles. Due to the secondary particles remaining during the film formation, particles / unsmooth coatings can be formed There will be results that are not practical. In order to ensure the stability of the basic properties of the plastisol, the stability of the plasticizer, and the flexibility of the coating film, various reviews were conducted. Because the form or nature of the particles such as the propionic acid polymer is not clearly defined As a substitute material for vinyl chloride, they are all of a low level, so they cannot currently reach the industrial practical level.

In Form 1, the diameter of the coarse pore is the diameter of the pore with the largest volume among the pores with a diameter greater than 1 μm, and the diameter of the micropore is the diameter of the pore with the largest volume among the pores with a diameter of 1 μιη Observe the relationship between the pore diameter and pore volume of the powder by mercury intrusion method. When the diameter of the coarse pores of the acrylic polymer powder is 7 μm or less and the diameter of the micro pores is 0.5 μm or less, the powder is less likely to be damaged when the acrylic sol is prepared, and as a result, storage stability or reduced fluidity can be prevented. When the diameters of the coarse pores and micro pores of the acrylic polymer powder are set in a predetermined range, they can usually satisfy the conditions of latex as 0.1. < [Solid component concentration X standard deviation (μιη) / average particle diameter of acrylic polymer particles in the latex (μχη)] and the conditions of latex spray drying < [(hot air inlet temperature-hot air outlet temperature) (° c) / acrylic poly -27-1240742 average particle size of the compound powder (pm)] < 1 ο The above solid content concentration is determined by measuring W2 / W1 when the latex is a certain mass (wi) and dried at 100 ° C for 3 hours, and the mass (W2) after drying is measured. The standard deviation indicates the standard deviation of the average particle diameter of acrylic polymer particles (primary particles). The acrylic polymer powder of Form 1 has a ratio (A / B) of coarse pore volume A (mL) to micropore pore volume B (mL) per 1 gram of 0.5 to 5, preferably, more preferably 0.6 ~ 2. The volume of the coarse pores and the volume of the fine pores were obtained by the mercury intrusion method. Here, the coarse pores refer to pores having a pore diameter of 1 μm or more, and the micro pores refer to pores having a diameter of 1 μm or less. Moreover, the volume of coarse pores and fine pores refers to the total pore volume of coarse pores, and the volume of micropores and pores refers to the total pore volume of micropores. When the above ratio is 0.5 to 5, absorption of the powder by the plasticizer can be controlled, and as a result, the decrease in the flowability of the acrylic sol or the expansion of the acrylic sol can be suppressed. The above-mentioned ratio A / B of the acrylic polymer powder is set in a predetermined range, and usually satisfies 〇 · 1 as a latex condition. < [Solid content concentration X standard deviation (μιη) / average particle diameter of acrylic polymer particles in the latex (μιη)] and spray drying conditions for the latex 〇 " < [(hot air inlet temperature-hot air outlet temperature) rc) / average particle diameter of propionic acid polymer powder hm)] < 10, and the above [solid content concentration x standard deviation (μιη) / average particle diameter of acrylic polymer particles in latex (pm)] is c, and the above [(hot air inlet kg-28-1240742) Degree-Hot Air Outlet Temperature) When (値 (:) / average particle diameter of acrylic polymer powder (μηι)] is D, 0.1CCXD (product of both) can be satisfied < 5. The application of the acrylic polymer powder according to the aspect 1 is not particularly limited, and it can be effectively used as a raw material for acrylic sol, resin modifier, powder coating, and the like. Among them, the acrylic polymer powder of Form 1 is particularly useful as a raw material of an acrylic sol. However, aspect 1 includes the above-mentioned acrylic polymer powder and a plasticizer.

(Ii) Acrylic polymer particles (1-1) are copolymer particles formed by polymerization at or above stages, and are obtained by forming a multi-stage polymer (I_b) in a latex containing a previous stage polymer (1-1-a). Multi-stage polymer particles, the pre-stage polymer (I -1-a) contains at least 20% by mass to 50% by mass of methyl methacrylate units in the outermost layer. Copolymers formed by different consecutive two or more stages of polymerization. The polymer (Ib) in the latter stage is a continuous two or more stages of polymerization that contains 50% by mass of methyl methacrylate units and differs from each other by one stage or monomer composition. The polymer formed is acrylic polymer particles having an agglomerate ratio of the first stage polymer (I-1_a) / post stage polymer (I_b) of 5/95 to 9δ / 5, and an acrylic polymer powder. Moreover, the proportion of the outermost outer layer of methyl methacrylate constituting the pre-stage polymer (丨 _;! _ A) is the same as that of the pre-stage polymer (Ia) in any of the forms 1, 2, or 3 The proportion of methyl acrylate units is the same. -48- 1240742 Acrylic polymer particles of form 5 (11_4 series are the same as the polymer (II-a) before the acrylic polymer particles (11) in form 1, form 2 or form 3, so they are prepared the same.) For polymers of acrylic polymer particles (Π-a), the glass transition temperature (Tg) is preferably below 50 ° C. When the Tg is below 50 ° C, a plasticizer can be obtained after the film is formed without seeping out of the film Acrylic sol on the surface of the film. The average particle diameter (primary particle diameter) of the acrylic polymer particles (II-a) is not particularly limited, and it is 0 · 〇1 ~; [〇μιη is better, and more preferably 〇 · 〇5〜1 μηι. The average particle size is 0. When it is more than 01 μm, the acrylic polymer particles (1 to 1) can be improved in dispersibility, and the surface of the formed film is excellent in smoothness. Form 5 acrylic polymer particles (1_1} pre-stage polymer οι-a) ′ Only with form 1, form 2 or 50% by mass of methyl methacrylate in the outermost layer The polymer (Ia) in the previous stage in any of the forms in 3 is different (the unit of methyl methacrylate in the polymer (I_a) in the previous stage is 5% to 50% by mass). The above-mentioned post-stage polymer (I-b) is the same as the post-stage polymer (I_b) of any of the forms 1, 2, and 3. However, the acrylic polymer particles (〖_〗) in the form 5 include the acrylic polymer particles in any of the forms 1, 2, and 3. The unit of methyl methacrylate in the outermost layer of the stage polymer (1-1-a) must be 20% by mass to 50% by mass, preferably 30% by mass to 50% by mass, and the best It is 35 to 50 mass%. When the unit of methyl methacrylate in the outermost layer of the polymerized polymer (B1-a) in the previous stage is less than 20% by mass, the latex containing the acrylic polymer particles of Form 5 is solidified and dried, and the polymer containing propionic acid is polymerized. The strength of the film formed by the acrylic sol of plastic powder and plasticizer is reduced by 49 to 1240742 degrees, so it is not desirable. When the methyl methacrylate unit is 50% by mass or more, the exudation resistance of the film surface is reduced, so it is not desirable. . The polymer at the previous stage (I-1-a) is composed of the methyl methacrylate unit and other monomers that can be copolymerized with methyl methacrylate. The "units copolymerizable with methyl methacrylate" in the constituent units of the polymer (Ia) in the previous stage in any of 2 or 3 are the same. The particle size (primary particle size) of the acrylic polymer particles (I -1) is not particularly limited. It is preferably 0.15 to 30 μm, and more preferably 0. 15 to 2 μm. When the particle diameter is in the above range, the acrylic polymer particles have good dispersibility and can improve the surface smoothness of the formed film. In the acrylic polymer powder according to the aspect 5, a latex containing acrylic polymer particles (II_a) and a latex containing acrylic polymer particles (1-; [) are mixed in a latex state, and the resultant is solidified and dried. Compared with the acrylic polymer powder formed by mixing two kinds of acrylic polymer powders obtained from various latexes, the acrylic polymer powder of form 5 has the advantage of uniform mixing state, and the dispersibility of the obtained acrylic sol is improved. And storage stability has been improved. The mixing ratio of the two types of latex in the aspect 5, the mass ratio of the acrylic polymer particles (II-a) / acrylic polymer particles (^ 丨) must be 5/95 ~ 4〇 / 60, preferably W95 ~ 3 5/65. When the compounding ratio of the acrylic polymer particles (n-a) is less than 5% by mass, the surface smoothness of the film formed by the poor dispersibility of the acrylic polymer particles (^ 丨) is reduced. Further, when the compounding ratio of the acrylic polymer particles (II-a) is more than 40% by mass, the strength of the film -50 to 1240742 after the film formation is reduced. Other advantages of Sadness 5 include, for example, the production of acrylic polymer particles (II-a) or acrylic polymer particles, the setting and drying of latex containing these, the production of acrylic sols, and the production of molded articles from acrylic sols. With < 1. Form 2 or Form 3 is performed in the same manner. When the effects of the above-mentioned aspect 5 are explained, the aspect 5 has the following effects in addition to the effects of the aspect 1, the shape 2 and the shape 3. In other words, the acrylic acid sol 'obtained by mixing the acrylic polymer powder of the form 5 with a plasticizer is excellent in storage stability. In addition, the molded product obtained from the acrylic acid sol is free of particles, has excellent surface smoothness, and unlike the molded product obtained from chloroethylene, does not generate hydrogen chloride gas upon burning.

Each comparative example failed to satisfy the necessary condition of the aspect 1 (void ratio) satisfied by the corresponding example (a condition that the integrated void volume of an acrylic polymer powder having a pore diameter of 1 μm or more was 0.9 mg / L or less), and In many of these comparative examples, the other necessary conditions (conditions of% porosity) of Form 1 were not satisfied (Table 4). As a result, the acrylic sols obtained in these examples were extremely excellent in fluidity and storage stability compared with the comparative examples (Table 5). In addition, Examples 1 to 4 of Examples 1 to 16 satisfy only the conditions of Form 1 (void ratio), Examples 1 to 5 satisfy only the conditions of Form 1 and Form 2 (particle size ratio), and Examples 16 only satisfy Relationship between the conditions of Form 1 and Form 3 (water-soluble polymer). The fluidity of the acrylic sol obtained in Example 15 compared with Example 14 was improved, and the particle rupture resistance of the acrylic sol obtained in Example 16 was increased compared to Example 14 (Table 5). Examples 20 to 22 have the same tendency. In other words, in Examples 20 to 22, Example 20 only satisfies the conditions of Form 1 (void ratio), Example 21 only satisfies the conditions of Form 1 and Form 2 (particle size ratio), and Example 22 only satisfies Forms 1 and 2. Correlation of the conditions of Form 3 (water-soluble polymer).
