RESIN COMPOSITION FOR IRREGULAR SHAPE EXTRUSION MOLDING AND IRREGULARLY SHAPED EXTRUSION MOLDED RESIN ARTICLE

摘要

Disclosed is a resin composition for irregular shape extrusion molding, which is capable of providing an irregularly shaped extrusion molded resin article that has excellent strength, impact resistance, heat resistance, scratch resistance, surface appearance and shape properties. Specifically disclosed is a resin composition for irregular shape extrusion molding, which contains a lubricant (C) and an inorganic filler (D) at predetermined ratios relative to an aromatic vinyl resin component that is composed of a rubber-reinforced aromatic vinyl resin (A) that is defined in item (1) below and an ultra high molecular weight aromatic vinyl resin (B) that is defined in item (2) below, said resins (A) and (B) being blended at a predetermined ratio. (1) A resin, which is composed of a graft polymer (a1) obtained by graft polymerizing an aromatic vinyl compound in the presence of a rubbery polymer, and if necessary, a polymer (a2) obtained by polymerizing an aromatic vinyl compound (provided that the amount of the polymer (a2) is not more than 90% by mass of the total mass of the polymers (a1) and (a2)), and which has an acetone-soluble content with a weight average molecular weight of not more than 1,000,000. (2) A resin, which is obtained by polymerizing a monomer component containing an aromatic vinyl compound, and which has an acetone-soluble content with a weight average molecular weight of not less than 2,000,000.
