THERMOPLASTIC RESIN COMPOSITION

摘要

PURPOSE: A styrenic thermoplastic resin composition is provided to improve the surface property while manufacturing a thin film extrusion sheet with a low contents of gel, and to maintain the tensile strength and the impact strength of the composition. CONSTITUTION: A styrenic thermoplastic resin composition contains 5~40 parts of rubber-modified graft copolymer by weight formed with a conjugated diene rubber latex, a methacrylic acid alkyl ester compound or an acrylic acid alkyl ester compound, a vinyl aromatic compound or a vinyl cyanide aromatic compound, and 50~90 parts of continuous bulk polymerized rubber-modified graft copolymer by weight. The rubber-modified graft copolymer has the average particle diameter of 0.2~0.5 micron.
