HEAT RESISTANT SAN LATEX, METHOD FOR PREPARING HEAT RESISTANT SAN RESIN, AND HEAT-RESISTANT ABS RESIN COMPOSITION

摘要

The present invention relates to a heat resistant SAN latex, a preparation method of a heat resistant SAN resin, and a heat resistant ABS resin composition. According to the present invention, the preparation method prepares a heat resistant ABS resin having excellent aggregation characteristics and productivity even under reduced usage of an emulsifier by adding an emulsifier auxiliary component to an emulsion polymerized heat resistant SAN latex. When the heat resistant SAN latex applied to an ABS resin, the ABS resin has improved gloss and heat resistance while maintaining impact strength. Provided are the preparation method for the heat resistant SAN resin, and a heat resistant ABS resin composition comprising the heat resistant SAN resin. The heat resistant SAN latex comprises: an α-methylstyrene monomer; a vinyl cyanide monomer; an aromatic vinyl monomer (excluding an α-methylstyrene monomer); a base resin; cyclic oligosaccharide; and an emulsifier.
