Heat-Resistant ABS Resin Composition With Excellent Processability and Resistance for Discoloration at High Temperature and Method for Preparing the Same

摘要

PURPOSE: A heat resistant ABS resin is provided to have excellent impact resistance, flowability, heat resistance, processability, and discoloration resistance. CONSTITUTION: A heat resistant ABS resin composition includes a rubber-modified graft copolymer graft polymerized of a cyanate vinyl-based monomer and aromatic vinyl-based monomer; 5-60 wt% of a vinyl-based copolymer polymerized of a vinyl-based monomer, and cyanide monomer; and 15-65 wt% of a terpolymer. The terpolymer is polymerized of 40-70 wt% ofα-alkylstyrene, 20-40 wt% of cyanate vinyl-based monomer, and 10-30 wt% of styrene.
