SAN SAN HEAT-RESISTANT SAN RESIN METHOD FOR PREPARING THE RESIN AND HEAT-RESISTANT SAN RESIN COMPOSITION COMPRISING THE SAME

摘要

The present invention relates to a heat-resistant SAN resin, a process for producing the same, and a heat-resistant SAN resin composition containing the same. More specifically, the present invention relates to a heat-resistant SAN resin comprising 52-78 wt.% Of alpha-methylstyrene, 20-40 wt.% Of a vinyl cyan compound, ) Acrylate, a method for producing the same, and a heat-resistant SAN resin composition containing the same. According to the present invention, there is provided a heat-resistant SAN resin having improved polymerization conversion ratio and increased weight average molecular weight while maintaining heat resistance, and a method for producing the same, and a heat-resistant SAN resin composition excellent in chemical resistance and excellent in mechanical properties and physical properties .
