ACRYLATE-STYRENE-ACRYLONITRILE RESIN COMPOSITION WITH EXCELLENT HIGH TEMPERATURE HEAT RESISTING DISCOLORATION PROPERTY AND A STATIONARY YELLOW INDEX AT HIGH TEMPERATURES WITHOUT DEGRADATION OF IMPACT STRENGTH, MOBILITY, AND WEATHER-RESISTANT

摘要

PURPOSE: An ASA (Acrylate-Styrene-Acrylonitrile) resin composition has characteristics of excellent high temperature heat resisting discoloration while maintaining impact strength, mobility, and weather-resistant.;CONSTITUTION: An ASA resin composition comprises 20-50 weight% of acrylic graft copolymers, 20-50 weight% of cyanide-aromatic vinyl copolymers having different molecular weights, and 30-50 weight% of alpha-methylstyrene terpolymers. The acrylic graft copolymer (A) is prepared by copolymerizing 40-60 weight% of acrylic rubber and 40-60 weight% of a monomer mixture of a vinyl aromatic compound and a vinyl cyanide compound. The acrylic rubber is a C2-10 alkyl acrylate. The average particle diameter of the rubber particle is 0.1-0.5 micron.;COPYRIGHT KIPO 2013
