WEATHER-RESISTANT RUBBER-MODIFIED VINYL-BASED GRAFT COPOLYMER WITH GOOD ELONGATION PROPERTY, HEAT-RESISTNCE, AND HARDNESS AND RESIN COMPOSITION THEREOF

摘要

PURPOSE: weather-proof rubber-modified vinyl-based graft copolymer offer ensures excellent heat resistance, tensile strength and hardness, maintains optical property. ;CONSTITUTION: the vinyl-based graft copolymer of modified rubber forms the vinyl cyanide monomer that resin is graft-polymerized and aromatic vinyl monomer introduces latex. The latex is that have glass transition temperature lower than room temperature (25 & deg by forming surface modified butadiene rubber and acrylic rubber; C groups). Partial size is 250-350 nanometers, butadiene rubber, which is one or more selected from least one of acrylonitrile, methacrylonitrile and ethyl acrylonitrile. ;The 2011 of copyright KIPO submissions
