Description

熱可塑性樹脂用の改質剤、樹脂組成物、水素化芳香族系炭化水素樹脂の使用、粘着付与剤及び粘・接着剤組成物Modifier for thermoplastic resin, resin composition, use of hydrogenated aromatic hydrocarbon resin, tackifier, and adhesive/adhesive composition
  本発明は、熱可塑性樹脂用の改質剤、樹脂組成物、水素化芳香族系炭化水素樹脂の使用、粘着付与剤及び粘・接着剤組成物に関する。 The present invention relates to a modifier for thermoplastic resins, a resin composition, the use of hydrogenated aromatic hydrocarbon resins, a tackifier, and a pressure-sensitive adhesive composition.
芳香族系石油樹脂、ピュアモノマー樹脂等の芳香族系炭化水素樹脂の水素化物（水素化芳香族系炭化水素樹脂）は、ポリオレフィン系樹脂やエンジニアリングプラスチック等の熱可塑性樹脂用の改質剤、ホットメルトや感圧型接着剤等の粘・接着剤用の粘着付与剤、塗料やインキ用のバインダー樹脂として、広く使用されている。 Hydrogenated aromatic hydrocarbon resins such as aromatic petroleum resins and pure monomer resins (hydrogenated aromatic hydrocarbon resins) are widely used as modifiers for thermoplastic resins such as polyolefin resins and engineering plastics, tackifiers for adhesives such as hot melts and pressure-sensitive adhesives, and binder resins for paints and inks.
上記熱可塑性樹脂は、工業的に様々な分野で用いられており、その中でも、エンジニアリングプラスチックやスーパーエンジニアリングプラスチックは、その優れた耐熱性と、強度のバランスから自動車材料、電気電子機器材料、住宅・建材材料として幅広く利用されている。一方で、上記熱可塑性樹脂、特にエンジニアリングプラスチックやスーパーエンジニアリングプラスチックは、成形加工温度が高く、溶融流動性に劣るものが多いため、通常は、熱可塑性樹脂に滑剤等の添加剤を添加することにより、溶融時における見かけの流動粘度を低下させて、成形加工性を向上させている（特許文献１、２）。 The above thermoplastic resins are used in various industrial fields, and among them, engineering plastics and super engineering plastics are widely used as automobile materials, electrical and electronic equipment materials, and housing and building materials due to their excellent balance of heat resistance and strength. On the other hand, the above thermoplastic resins, particularly engineering plastics and super engineering plastics, often have high molding temperatures and poor melt fluidity, so additives such as lubricants are usually added to the thermoplastic resins to reduce the apparent flow viscosity during melting and improve molding processability (Patent Documents 1 and 2).
また、上記粘・接着剤は、アクリル系重合体、ゴム系エラストマー（天然ゴム、合成ゴム）、エチレン－酢酸ビニル共重合体等のベースポリマーを主成分とするものであるが、一般にベースポリマーだけではさまざまな被着体に対する接着力が不十分なため、ロジンエステル、各種石油樹脂、テルペン樹脂等の粘着付与剤を配合した組成物として用いられている（特許文献３）。 The above-mentioned adhesives and pressure-sensitive adhesives are primarily composed of base polymers such as acrylic polymers, rubber-based elastomers (natural rubber, synthetic rubber), and ethylene-vinyl acetate copolymers. However, because the base polymer alone generally does not provide sufficient adhesive strength to various adherends, these adhesives are used as compositions containing tackifiers such as rosin esters, various petroleum resins, and terpene resins (Patent Document 3).

しかしながら、熱可塑性樹脂においては、従来の滑剤を用いた場合であっても、溶融時の流動性が未だに不十分であり、成形加工性に劣るものがある。また、熱可塑性樹脂、特にエンジニアリングプラスチックやスーパーエンジニアリングプラスチックにおいては、それらの融点が凡そ２００℃以上と高いため、高温下（２５０℃以上）にて溶融させるが、従来の滑剤を添加すると溶融の際に発煙が生じる場合がある。 However, even when conventional lubricants are used, some thermoplastic resins still have insufficient fluidity when melted, resulting in poor moldability. Furthermore, thermoplastic resins, particularly engineering plastics and super engineering plastics, have high melting points of approximately 200°C or higher, and are melted at high temperatures (250°C or higher). However, the addition of conventional lubricants can cause smoke during melting.
また、粘・接着剤においては、従来の粘着付与剤を使用した場合であっても、接着力が十分でないものがある。さらに、従来の粘着付与剤を使用した粘・接着剤においては、その製造や使用の際に臭気を発する場合がある。 In addition, some adhesives and pressure-sensitive adhesives do not have sufficient adhesive strength even when conventional tackifiers are used. Furthermore, adhesives and pressure-sensitive adhesives that use conventional tackifiers may emit an odor during production and use.
そこで、本発明は、熱可塑性樹脂の溶融時の発煙を抑制し、熱可塑性樹脂の成形加工性を向上し得る、新規な熱可塑性樹脂用の改質剤を提供することを目的とする。 The present invention aims to provide a novel modifier for thermoplastic resins that can suppress smoke generation during melting of the thermoplastic resin and improve the molding processability of the thermoplastic resin.
また、本発明は、粘・接着剤における臭気を抑制し、粘・接着剤に高い接着力を付与し得る、新規な粘着付与剤を提供することを目的とする。 The present invention also aims to provide a novel tackifier that can suppress odors in adhesives and provide high adhesive strength to adhesives and adhesives.

Examples of the mass residual rate of the hydrogenated aromatic hydrocarbon resin include 100 mass%, 99 mass%, 98 mass%, 97 mass%, 96 mass%, 95 mass%, 94 mass%, 93 mass%, 92 mass%, 91 mass%, 90 mass%, 89 mass%, 88 mass%, 87 mass%, 86 mass%, 85 mass%, 84 mass%, 83 mass%, 82 mass%, 81 mass%, 80 mass%, 79 mass%, 78 mass%, 77 mass%, 76 mass%, 75 mass%, 74 mass%, 73 mass%, 72 mass%, 71 mass%, 70 mass%, 69 mass%, 68 mass%, 67 mass%, 66 mass%, 65 mass%, and 64 mass%, etc. In one embodiment, the mass residual ratio of the hydrogenated aromatic hydrocarbon resin is preferably 64% by mass or more, more preferably 70% by mass or more, even more preferably 80% by mass or more, still more preferably 90% by mass or more, and particularly preferably 100% by mass, from the viewpoint of suppressing smoke generation during melting of the thermoplastic resin. The higher the mass residual ratio of the hydrogenated aromatic hydrocarbon resin, the more smoke generation during melting of the thermoplastic resin can be suppressed.
なお、本開示において、上記質量残留率は、後述の実施例に記載の方法で測定されるものである。 In this disclosure, the mass retention rate is measured by the method described in the Examples below.
熱可塑性樹脂、特にエンジニアリングプラスチックやスーパーエンジニアリングプラスチックにおいては、それらの成形加工温度は２５０℃以上である場合が多い。本発明者らは、水素化芳香族系炭化水素樹脂を熱可塑性樹脂に用いて、その溶融時において発煙する場合、水素化芳香族系炭化水素樹脂が成形加工温度において揮発し得る成分及び熱分解し得る構造を多く有しているために、その揮発成分及び熱分解物により発煙が生じると推察した。そして、本発明者らは、水素化芳香族系炭化水素樹脂について、成形加工温度と同等又はそれ以上の温度（３００℃）で、且つ長時間（２時間）加熱する過酷な条件下での質量残留率を評価し、その質量残留率が６４質量％以上のものは、そのような成分や構造が少ないために、熱可塑性樹脂の成形加工において使用しても発煙が抑制されることを見出した。 The molding temperature of thermoplastic resins, particularly engineering plastics and super engineering plastics, is often 250°C or higher. The present inventors have hypothesized that when hydrogenated aromatic hydrocarbon resins are used as thermoplastic resins and emit smoke when melted, the hydrogenated aromatic hydrocarbon resins have many components that can volatilize and structures that can thermally decompose at the molding temperature, and therefore the smoke is generated by the volatile components and thermal decomposition products. The present inventors have evaluated the mass retention rate of hydrogenated aromatic hydrocarbon resins under harsh conditions of heating at a temperature (300°C) equal to or higher than the molding temperature for a long period of time (2 hours), and have found that those with a mass retention rate of 64% or more have few such components and structures, and therefore suppress smoke generation even when used in the molding of thermoplastic resins.
そして、水素化芳香族系炭化水素樹脂においては、成形加工温度において揮発し得る成分や熱分解し得る構造について、その詳細は多岐にわたり特定するのは困難であるため、本発明者らは、上記質量残留率で水素化芳香族系炭化水素樹脂を規定することにより、熱可塑性樹脂の溶融時における発煙を抑制し得るものを特定している。 In addition, since it is difficult to specify the details of hydrogenated aromatic hydrocarbon resins, such as the components that may volatilize at molding processing temperatures and the structures that may thermally decompose, the inventors have specified hydrogenated aromatic hydrocarbon resins that can suppress smoke generation when the thermoplastic resin is melted by defining the hydrogenated aromatic hydrocarbon resins based on the above mass residual ratio.
　なお、上記質量残留率において加熱温度が３００℃より低い場合、及び／又は、加熱時間が２時間より短い場合、加熱条件が温和なために、水素化芳香族系炭化水素樹脂においては、熱可塑性樹脂の溶融時における発煙の傾向を適切に評価することが困難となる。また、熱可塑性樹脂の溶融時に発煙する場合、発煙による装置汚れ・金型汚れが発生するが、加熱時間が２時間より短いと、実際の成形加工における装置汚れ・金型汚れを反映できないため、それら汚れ具合を適切に評価することが困難となる。 When the heating temperature is lower than 300°C and/or the heating time is shorter than 2 hours at the above mass retention rate, the heating conditions are mild, making it difficult to properly evaluate the tendency of hydrogenated aromatic hydrocarbon resins to emit smoke when the thermoplastic resin is melted. In addition, when the thermoplastic resin emits smoke when melted, the smoke causes equipment and mold contamination, but when the heating time is shorter than 2 hours, it is difficult to properly evaluate the degree of contamination because it is not possible to reflect the equipment and mold contamination that occurs in actual molding processing.
上記水素化芳香族系炭化水素樹脂の上記質量残留率が６４質量％未満である場合は、熱可塑性樹脂に使用すると、その溶融時において発煙が多く発生する傾向にある。 If the mass residual ratio of the hydrogenated aromatic hydrocarbon resin is less than 64 mass%, when it is used in a thermoplastic resin, it tends to emit a lot of smoke when melted.
上記水素化芳香族系炭化水素樹脂のＭＭＡＰは、例えば、３９℃、３８℃、３７℃、３６℃、３５℃、３４℃、３３℃、３２℃、３１℃、３０℃、２９℃、２８℃、２７℃、２６℃、２５℃、２４℃、２３℃、２２℃、２１℃、２０℃、１９℃、１８℃、１７℃、１６℃、１５℃、１４℃、１３℃、１２℃、１１℃、１０℃、９℃、８℃、７℃、６℃、５℃等が挙げられる。１つの実施形態において、上記水素化芳香族系炭化水素樹脂のＭＭＡＰは、熱可塑性樹脂の溶融時における流動性を向上させる点から、好ましくは５℃以上４０℃未満が挙げられ、より好ましくは５℃～３５℃が挙げられ、さらに好ましくは５～２０℃が挙げられる。 The MMAP of the hydrogenated aromatic hydrocarbon resin may be, for example, 39°C, 38°C, 37°C, 36°C, 35°C, 34°C, 33°C, 32°C, 31°C, 30°C, 29°C, 28°C, 27°C, 26°C, 25°C, 24°C, 23°C, 22°C, 21°C, 20°C, 19°C, 18°C, 17°C, 16°C, 15°C, 14°C, 13°C, 12°C, 11°C, 10°C, 9°C, 8°C, 7°C, 6°C, or 5°C. In one embodiment, the MMAP of the hydrogenated aromatic hydrocarbon resin is preferably 5°C or more and less than 40°C, more preferably 5°C to 35°C, and even more preferably 5°C to 20°C, in order to improve the fluidity of the thermoplastic resin when melted.

If the proportion of aromatic parts in the hydrogenated aromatic hydrocarbon resin is high, the MMAP tends to be low, and if the proportion of aromatic parts is low, the MMAP tends to be high.
上記水素化芳香族系炭化水素樹脂のＭＭＡＰが５℃未満である場合、又は、ＭＭＡＰが４０℃以上である場合、熱可塑性樹脂の溶融時における流動性が低下する傾向にある。 If the MMAP of the hydrogenated aromatic hydrocarbon resin is less than 5°C, or if the MMAP is 40°C or higher, the flowability of the thermoplastic resin when melted tends to decrease.

（水素化芳香族系炭化水素樹脂の製造方法）
　上記水素化芳香族系炭化水素樹脂は、各種公知の手段を用いて得ることができる。具体的には、例えば、公知の水素化条件を用いて、各種公知の芳香族系炭化水素樹脂を水素化することにより得ることができる。 (Method for producing hydrogenated aromatic hydrocarbon resin)
The hydrogenated aromatic hydrocarbon resin can be obtained by any of various known means. Specifically, for example, the hydrogenated aromatic hydrocarbon resin can be obtained by hydrogenating any of various known aromatic hydrocarbon resins under known hydrogenation conditions.
上記芳香族系炭化水素樹脂は、例えば、上記芳香族系石油樹脂、上記ピュアモノマー樹脂等が挙げられる。 Examples of the aromatic hydrocarbon resin include the aromatic petroleum resin and the pure monomer resin.
　水素化条件は、例えば、水素化触媒の存在下、水素分圧が０．２～３０ＭＰａ程度で、２００～３５０℃程度に、上記芳香族系炭化水素樹脂を加熱する方法等が挙げられる。水素化触媒としては、例えば、ニッケル、パラジウム、コバルト、ルテニウム、白金及びロジウム等の金属や、該金属の酸化物が挙げられる。１つの実施形態において、水素化触媒の使用量は、原料樹脂１００質量部に対して、好ましくは０．０１～１０質量部程度が挙げられる。 The hydrogenation conditions include, for example, a method in which the aromatic hydrocarbon resin is heated to about 200 to 350°C in the presence of a hydrogenation catalyst at a hydrogen partial pressure of about 0.2 to 30 MPa. Examples of the hydrogenation catalyst include metals such as nickel, palladium, cobalt, ruthenium, platinum, and rhodium, and oxides of these metals. In one embodiment, the amount of the hydrogenation catalyst used is preferably about 0.01 to 10 parts by mass per 100 parts by mass of the raw material resin.
　上記水素化は、上記芳香族系炭化水素樹脂を溶融して、又は溶剤に溶解した状態で行う。該石油樹脂を溶解する溶剤は特に限定されないが、反応に不活性で原料や生成物が溶解し易い溶剤であればよい。例えば、シクロヘキサン、ｎ－ヘキサン、ｎ－ヘプタン、デカリン、テトラヒドロフラン、ジオキサン等を１種または２種以上を組み合わせて使用できる。１つの実施形態において、溶剤の使用量は、通常、該石油樹脂に対して固形分１０質量％以上が挙げられ、好ましくは１０～７０質量％が挙げられる。なお、上記水素化条件は反応形式として回分式を採用した場合について説明しているが、反応形式としては流通式（固定床式、流動床式等）を採用することもできる。 The above hydrogenation is carried out with the aromatic hydrocarbon resin melted or dissolved in a solvent. The solvent for dissolving the petroleum resin is not particularly limited, but any solvent that is inert to the reaction and easily dissolves the raw materials and products may be used. For example, cyclohexane, n-hexane, n-heptane, decalin, tetrahydrofuran, dioxane, etc. can be used alone or in combination of two or more. In one embodiment, the amount of solvent used is usually 10% by mass or more of solids relative to the petroleum resin, and preferably 10 to 70% by mass. Note that the above hydrogenation conditions are described for a batch-type reaction format, but a flow-type reaction format (fixed bed type, fluidized bed type, etc.) can also be used.
　上記水素化においては、上記芳香族系炭化水素樹脂の芳香環に対する水素化率を調整することにより、上記水素化芳香族系炭化水素樹脂の芳香族水素の含有率を適宜設定できる。具体的には、当該芳香環に対する水素化率が高い程、上記芳香族水素の含有率は低くなり、当該芳香環に対する水素化率が低い程、上記芳香族水素の含有率は高くなる。 In the hydrogenation, the content of aromatic hydrogen in the hydrogenated aromatic hydrocarbon resin can be appropriately set by adjusting the hydrogenation rate of the aromatic rings of the aromatic hydrocarbon resin. Specifically, the higher the hydrogenation rate of the aromatic rings, the lower the content of aromatic hydrogen, and the lower the hydrogenation rate of the aromatic rings, the higher the content of aromatic hydrogen.
なお、上記芳香族系炭化水素樹脂の芳香環に対する水素化率は、ＮＭＲ測定法により求められ、上記芳香族系炭化水素樹脂及びそれから得られる水素化芳香族系炭化水素樹脂の１Ｈ－ＮＭＲの７ｐｐｍ付近に現れる芳香環由来のＨ－スペクトル面積から以下の式に基づき算出する。
 
水素化率＝｛１－（水素化芳香族系炭化水素樹脂の１Ｈ－ＮＭＲの７ｐｐｍ付近に現れる芳香環由来のＨ－スペクトル面積／芳香族系炭化水素樹脂の１Ｈ－ＮＭＲの７ｐｐｍ付近に現れる芳香環由来のＨ－スペクトル面積）｝×１００（％）。 The hydrogenation rate of the aromatic rings in the aromatic hydrocarbon resin is determined by NMR measurement and calculated based on the following formula from the H-spectrum area derived from the aromatic rings appearing at about 7 ppm in 1H -NMR of the aromatic hydrocarbon resin and the hydrogenated aromatic hydrocarbon resin obtained therefrom.

Hydrogenation rate={1-(H-spectrum area derived from aromatic rings appearing near 7 ppm in 1 H-NMR of hydrogenated aromatic hydrocarbon resin/H-spectrum area derived from aromatic rings appearing near 7 ppm in 1 H-NMR of aromatic hydrocarbon resin)}×100 (%).
　また、上記水素化においては、上記芳香族系炭化水素樹脂に含まれるオレフィン性二重結合のほぼ全てが水素化される。なお、当該オレフィン性二重結合には、芳香環における炭素－炭素二重結合は含まれない。 In addition, in the hydrogenation, almost all of the olefinic double bonds contained in the aromatic hydrocarbon resin are hydrogenated.

（樹脂組成物の製造方法）
　上記樹脂組成物の製造方法は、特に限定されず、各種公知の方法を採用できる。上記樹脂組成物の製造方法は、例えば、上記改質剤（又は上記水素化芳香族系炭化水素樹脂）、上記熱可塑性樹脂、並びに必要に応じて上記フィラー及び上記添加剤を、タンブラーミキサーやヘンシェルミキサーなどの各種混合機を用い予め混合した後、バンバリーミキサー、ロール、ブラベンダー、単軸混練押出機、二軸混練押出機、ニーダーなどの混合機で溶融混練する方法が挙げられる。当該溶融混練の温度は、特に制限されないが、通常、上記熱可塑性樹脂の融点－３０℃～融点＋３０℃の範囲である。 (Method for producing resin composition)
The method for producing the resin composition is not particularly limited, and various known methods can be adopted. The method for producing the resin composition includes, for example, a method in which the modifier (or the hydrogenated aromatic hydrocarbon resin), the thermoplastic resin, and, if necessary, the filler and the additives are mixed in advance using various mixers such as a tumbler mixer or a Henschel mixer, and then melt-kneaded using a mixer such as a Banbury mixer, a roll, a Brabender, a single-screw kneading extruder, a twin-screw kneading extruder, or a kneader. The temperature of the melt-kneading is not particularly limited, but is usually in the range of the melting point of the thermoplastic resin -30 ° C to the melting point +30 ° C.
　上記樹脂組成物の製造においては、上記改質剤又は上記水素化芳香族系炭化水素樹脂を使用することにより、樹脂組成物の溶融混練時における流動性が高くなるため、生産性に優れる。また、従来、フィラーを含む樹脂組成物においては、フィラーによって樹脂組成物の溶融粘度が非常に高くなるため、溶融混練時における流動性が極端に低下するが、上記改質剤又は上記水素化芳香族系炭化水素樹脂を使用すると、フィラーを含む樹脂組成物の製造においても、溶融混練時における流動性が高くなる。 In the production of the resin composition, the use of the modifier or the hydrogenated aromatic hydrocarbon resin increases the fluidity of the resin composition when melt-kneaded, resulting in excellent productivity. Furthermore, in conventional resin compositions containing fillers, the filler makes the resin composition have a very high melt viscosity, which significantly reduces the fluidity when melt-kneaded. However, when the modifier or the hydrogenated aromatic hydrocarbon resin is used, the fluidity when melt-kneaded is increased, even in the production of a resin composition containing a filler.
また、上記樹脂組成物の製造においては、上記改質剤又は上記水素化芳香族系炭化水素樹脂を使用しても、溶融混練時における発煙が抑制されている。 In addition, when the resin composition is produced using the modifier or the hydrogenated aromatic hydrocarbon resin, smoke emission during melt kneading is suppressed.

（水素化芳香族系炭化水素樹脂の物性）

Examples of the mass residual rate of the hydrogenated aromatic hydrocarbon resin include 100 mass%, 99 mass%, 98 mass%, 97 mass%, 96 mass%, 95 mass%, 94 mass%, 93 mass%, 92 mass%, 91 mass%, 90 mass%, 89 mass%, 88 mass%, 87 mass%, 86 mass%, 85 mass%, 84 mass%, 83 mass%, 82 mass%, 81 mass%, 80 mass%, 79 mass%, 78 mass%, 77 mass%, 76 mass%, 75 mass%, 74 mass%, 73 mass%, 72 mass%, 71 mass%, 70 mass%, 69 mass%, 68 mass%, 67 mass%, 66 mass%, 65 mass%, and 64 mass%, etc. In one embodiment, the mass residual rate of the hydrogenated aromatic hydrocarbon resin is preferably 64 mass% or more, more preferably 70 mass% or more, even more preferably 80 mass% or more, even more preferably 90 mass% or more, and particularly preferably 100 mass% from the viewpoint of suppressing odor in the pressure-sensitive adhesive or adhesive. The higher the mass residual rate of the hydrogenated aromatic hydrocarbon resin, the more odor in the pressure-sensitive adhesive or adhesive can be suppressed.
なお、本開示において、上記質量残留率は、後述の実施例に記載の方法で測定されるものである。 In this disclosure, the mass retention rate is measured by the method described in the Examples below.
本発明者らは、粘・接着剤の製造及び／又は使用において臭気を発する場合、粘・接着剤に使用される粘着付与剤がそのような臭気を発していることを見出し、そして驚くべきことに、上記質量残留率が６４質量％以上である水素化芳香族系炭化水素樹脂を粘・接着剤に使用すると、粘・接着剤の製造及び／又は使用において臭気を抑制し得ることを見出した。粘・接着剤において臭気が抑制される詳細は不明だが、上記質量残留率が６４質量％以上である水素化芳香族系炭化水素樹脂は、臭気の原因となる揮発成分、及び／又は、粘・接着剤の製造・使用時の加熱における分解物が少ないためと推察される。 The inventors have found that when an odor is generated during the production and/or use of an adhesive, it is the tackifier used in the adhesive that emits such an odor, and have surprisingly found that the use of a hydrogenated aromatic hydrocarbon resin having a mass residual rate of 64% or more in the adhesive can suppress odor during the production and/or use of the adhesive. Although the details of how odor is suppressed in the adhesive are unclear, it is presumed that this is because hydrogenated aromatic hydrocarbon resins having a mass residual rate of 64% or more contain less volatile components that cause odor and/or decomposition products that are generated when heated during the production and use of the adhesive.
そして、水素化芳香族系炭化水素樹脂においては、臭気の原因となる揮発成分、及び／又は、粘・接着剤の製造・使用時の加熱における分解物について、その詳細は多岐にわたり特定するのは困難であるため、本発明者らは、上記質量残留率で水素化芳香族系炭化水素樹脂を規定することにより、粘・接着剤の製造及び／又は使用における臭気を抑制し得るものを特定している。 In addition, with hydrogenated aromatic hydrocarbon resins, the details of the volatile components that cause odors and/or decomposition products that occur when heated during the production and use of adhesives are diverse and difficult to identify, so the inventors have specified hydrogenated aromatic hydrocarbon resins based on the above mass residual rate, thereby identifying those that can suppress odors during the production and/or use of adhesives.
　なお、上記質量残留率において加熱温度が３００℃より低い場合、及び／又は、加熱時間が２時間より短い場合、加熱条件が温和なために、水素化芳香族系炭化水素樹脂においては、粘・接着剤の製造及び／又は使用における臭気の傾向を適切に評価することが困難となる。 If the heating temperature is lower than 300°C and/or the heating time is shorter than 2 hours at the above mass retention rate, the heating conditions are mild, making it difficult to properly evaluate the odor tendency in the manufacture and/or use of the adhesive for hydrogenated aromatic hydrocarbon resins.
上記水素化芳香族系炭化水素樹脂の上記質量残留率が６４質量％未満である場合は、粘・接着剤に使用すると、その製造及び／又は使用において臭気を発する傾向にある。 If the mass residual rate of the hydrogenated aromatic hydrocarbon resin is less than 64 mass%, when it is used in a pressure-sensitive adhesive, it tends to emit an odor during its production and/or use.
上記水素化芳香族系炭化水素樹脂のＭＭＡＰは、例えば、３９℃、３８℃、３７℃、３６℃、３５℃、３４℃、３３℃、３２℃、３１℃、３０℃、２９℃、２８℃、２７℃、２６℃、２５℃、２４℃、２３℃、２２℃、２１℃、２０℃、１９℃、１８℃、１７℃、１６℃、１５℃、１４℃、１３℃、１２℃、１１℃、１０℃、９℃、８℃、７℃、６℃、５℃等が挙げられる。１つの実施形態において、上記水素化芳香族系炭化水素樹脂のＭＭＡＰは、粘・接着剤における接着力を向上させる点から、好ましくは５℃以上４０℃未満が挙げられ、より好ましくは５℃～３５℃が挙げられ、さらに好ましくは５～２０℃が挙げられる。 The MMAP of the hydrogenated aromatic hydrocarbon resin may be, for example, 39°C, 38°C, 37°C, 36°C, 35°C, 34°C, 33°C, 32°C, 31°C, 30°C, 29°C, 28°C, 27°C, 26°C, 25°C, 24°C, 23°C, 22°C, 21°C, 20°C, 19°C, 18°C, 17°C, 16°C, 15°C, 14°C, 13°C, 12°C, 11°C, 10°C, 9°C, 8°C, 7°C, 6°C, or 5°C. In one embodiment, the MMAP of the hydrogenated aromatic hydrocarbon resin is preferably 5°C or more and less than 40°C, more preferably 5°C to 35°C, and even more preferably 5°C to 20°C, in order to improve the adhesive strength of the adhesive.
なお、本開示において、ＭＭＡＰは、後述の実施例に記載の方法で測定されるものである。 Note that in this disclosure, MMAP is measured by the method described in the Examples below.
上記水素化芳香族系炭化水素樹脂のＭＭＡＰは、上記水素化芳香族系炭化水素樹脂における芳香族性の特質を示すものである。上記水素化芳香族系炭化水素樹脂における芳香族部分の割合が高いと、ＭＭＡＰは低い傾向にあり、芳香族部分の割合が低いと、ＭＭＡＰは高い傾向にある。 The MMAP of the hydrogenated aromatic hydrocarbon resin indicates the aromatic characteristics of the hydrogenated aromatic hydrocarbon resin. If the proportion of aromatic parts in the hydrogenated aromatic hydrocarbon resin is high, the MMAP tends to be low, and if the proportion of aromatic parts is low, the MMAP tends to be high.
上記水素化芳香族系炭化水素樹脂のＭＭＡＰが５℃未満である場合、又は、ＭＭＡＰが４０℃以上である場合、粘・接着剤における接着力が低下する傾向にある。 If the MMAP of the hydrogenated aromatic hydrocarbon resin is less than 5°C, or if the MMAP is 40°C or higher, the adhesive strength of the pressure-sensitive adhesive tends to decrease.

上記水素化芳香族系炭化水素樹脂の重量平均分子量が高い程、上記質量残留率は高い傾向にある。 The higher the weight average molecular weight of the hydrogenated aromatic hydrocarbon resin, the higher the mass retention rate tends to be.

［粘着付与剤としての使用］
　上記水素化芳香族系炭化水素樹脂は、粘・接着剤に用いる粘着付与剤として使用することができる。上記水素化芳香族系炭化水素樹脂を粘・接着剤に使用すると、粘・接着剤における接着力を向上させる。粘・接着剤は、特に限定されず、例えば、前述のものが挙げられる。 [Use as a tackifier]
The hydrogenated aromatic hydrocarbon resin can be used as a tackifier for adhesives. When the hydrogenated aromatic hydrocarbon resin is used in an adhesive, the adhesive strength of the adhesive is improved. The adhesive is not particularly limited, and examples thereof include those mentioned above.
１つの実施形態において、上記水素化芳香族系炭化水素樹脂は、粘・接着剤における接着力をより向上させる点から、好ましくはアクリル系粘・接着剤組成物に用いる粘着付与剤として使用される。 In one embodiment, the hydrogenated aromatic hydrocarbon resin is preferably used as a tackifier in an acrylic pressure-sensitive adhesive composition in order to further improve the adhesive strength of the pressure-sensitive adhesive.
　アクリル系粘・接着剤組成物に用いる粘着付与剤としての上記水素化芳香族系炭化水素樹脂の使用量は、特に限定されない。当該水素化芳香族系炭化水素樹脂の使用量は、例えば、上述した上記粘着付与剤の使用量等が挙げられる。 The amount of the hydrogenated aromatic hydrocarbon resin used as a tackifier in the acrylic adhesive composition is not particularly limited. Examples of the amount of the hydrogenated aromatic hydrocarbon resin used include the amount of the tackifier used described above.
また、従来の粘着付与剤においては、活性エネルギー線硬化型アクリル系粘・接着剤組成物に使用した場合に、紫外線等の活性エネルギー線を吸収して、アクリル系モノマー及びアクリル系オリゴマーの重合反応を阻害（以下、重合阻害とも記す）するものがあり、それによって当該粘・接着剤組成物の接着力が低下する問題があった。１つの実施形態において、上記水素化芳香族系炭化水素樹脂は、上記オレフィン含有率が低い又は０であるため、アクリル系モノマー及びアクリル系オリゴマーの重合阻害を抑制し得ることから、好ましくは活性エネルギー線硬化型アクリル系粘・接着剤組成物に用いる粘着付与剤として使用される。 Furthermore, some conventional tackifiers, when used in active energy ray-curable acrylic pressure-sensitive adhesive compositions, absorb active energy rays such as ultraviolet rays and inhibit the polymerization reaction of acrylic monomers and acrylic oligomers (hereinafter also referred to as polymerization inhibition), which causes a problem of a decrease in the adhesive strength of the pressure-sensitive adhesive composition. In one embodiment, the hydrogenated aromatic hydrocarbon resin has a low or zero olefin content and can suppress the polymerization inhibition of acrylic monomers and acrylic oligomers, and is therefore preferably used as a tackifier for use in active energy ray-curable acrylic pressure-sensitive adhesive compositions.
上記活性エネルギー線硬化型アクリル系粘・接着剤組成物に用いる粘着付与剤としての上記水素化芳香族系炭化水素樹脂の使用量は、特に限定されない。当該水素化芳香族系炭化水素樹脂の使用量は、例えば、上述した上記活性エネルギー線硬化型アクリル系粘・接着剤組成物における水素化芳香族系炭化水素樹脂の含有量等が挙げられる。 The amount of the hydrogenated aromatic hydrocarbon resin used as a tackifier in the active energy ray-curable acrylic pressure-sensitive adhesive composition is not particularly limited. Examples of the amount of the hydrogenated aromatic hydrocarbon resin used include the content of the hydrogenated aromatic hydrocarbon resin in the active energy ray-curable acrylic pressure-sensitive adhesive composition.
