Title:
HEAT RESISTANT SAN RESIN, PREPARATION METHOD THEREFOR, AND HEAT RESISTANT SAN RESIN COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2016/175423
Kind Code:
A1
Abstract:
The present invention relates to a heat resistant SAN resin, a preparation method therefor, and a heat resistant SAN resin composition containing the same and, more specifically, to a heat resistant SAN resin obtained by the polymerization of 52-78 wt% of α-methylstyrene, 20-40 wt% of a vinyl cyanide compound and 2-8 wt% of a hydroxyalkyl (meth)acrylate, a preparation method therefor, and a heat resistant SAN resin composition containing the same. According to the present invention, there are effects of providing a heat resistant SAN resin, which has an improved polymerization conversion rate while maintaining heat resistance and an increased weight average molecular weight, and a preparation method therefor, and providing a heat resistant SAN resin composition containing the same and having remarkable chemical resistance and excellent mechanical properties and a physical property balance.
