ポリマーのブレンドは余り進展していない状況であ。(Prior Art) In recent years, melt molding of polyarylene sulfide (hereinafter referred to as PAS) to make fibers, films, porous membranes, etc. has begun. Since RAS has extremely high chemical resistance and heat resistance, it is widely used in various applications. However, it has been pointed out that the strength is somewhat weak and that it is brittle. In addition, since PAS is expensive, it is often blended with other polymers, and when blended with other thermoplastic polymers to bring out the characteristics of both, RAS often has a high melting point and high viscosity. A major problem was that the polymer thermally decomposed. For this reason, surprisingly little progress has been made in blending PAS with other polymers.

In the formula, when () is added, an alkyl group or the like outside () may be attached to any phenyl group in (). Further, in such a structural formula, a halogen group such as chlorine may be attached to a part thereof. In addition, when the additive has a halogen group, there is a great advantage that the heat resistance of the additive is dramatically improved.

明の方法は極めて有効である。That is, the additives may be press-injected or adsorbed after melt molding, but those added during melt molding are particularly preferred. When added during melt molding, the melt viscosity is lowered, so there is no need to unnecessarily heat the molding process, and the decomposition of the polymer can be significantly suppressed. The method of the present invention is particularly effective when blending with a low melting point polymer.

Addition and mixing can be performed by a conventionally known method and is not particularly limited. In particular, in the case of a blend, it is necessary to determine the amount of addition by sufficiently determining the properties of both blend polymers. Naturally, it is necessary to select additives by considering the physical properties of both blend polymers. Melt molding in the present invention refers to melt-fiber formation, melt-film formation,
It includes all methods such as melting, decomposition, and molding into three-dimensional objects, and is not particularly limited.

めった。When a stretching test was conducted in the same manner, the stretching ratio was only up to 2.8 times, and the strength was also somewhat weak at 4.3 g/d. In addition, a bending strength test was conducted to check the durability, and when Comparative Example 1 was set as 100, Example 1 was extremely strong and had a high durability of 250. Also -10'C
When a similar bending test was carried out, the bending strength was as strong as 238, and the cold resistance was high. On the other hand, the bending strength of Comparative Example 1 at -10'C was 76, which was rather weak, and was disappointing.

超極細１繊維が得られた。Example 2 A special spinning machine was used to create a polymer mutual array, and the sea component was polystyrene produced by Asahi Kasei Industries, Inc., Kuipro 85, and the island component was the additive polymer of Example 1.
Melt spinning was carried out at C at a spinning speed of 1000 m/min. Spinning was carried out smoothly, and there were no 1 to 10 rubs at all. Next, when a stretching test was conducted, it was possible to stretch the film to 3°818. When the rough sea component was dissolved and removed with 1-hercrene, the drawn yarn had an extremely high strength of 5.7 q/d, and an ultra-fine 1-fiber of 0.01 denier was obtained.

As expected, it was extremely strong.

即ち、良好な複合繊維（複合体）が１７られだ。That is, 17 good composite fibers (composite materials) were obtained.

、強度も脱海俊で３．８ｇ／ｄとやや弱い物であった。Therefore, when spinning was carried out at 320° C. in the same manner as in Example 1, the polystyrene produced extremely smoke (presumably due to the polystyrene molecular R-shape), and yarn breakage was too severe to allow spinning. Therefore, when the spinning temperature was lowered to 315°C, although smoke was inevitably emitted from the polystyrene, spinning was somehow possible. However, the drawing ratio A8 increased only to 2.5 times, and the strength was a little weak at 3.8 g/d.

A plate-shaped product was made by melt-molding at 0°C. There were no particular troubles during the process, and the obtained plate-shaped product did not have any voids or the like, and was an extremely good molded product that could be used as a variety of molding materials.

実施例３において添加剤を入れないで溶融成形したとこ
ろ、ＰＰＳが十分に溶融せず、溶融成形できなかった。Comparative Example 3 When melt molding was performed in Example 3 without adding any additives, PPS was not sufficiently melted and melt molding could not be performed.
