SAN SAN ABS METHOD FOR PRODUCING HEAT RESISTANCE SAN RESIN HEAT RESISTANCE SAN RESIN AND HEAT RESISTANCE ABS RESIN

摘要

The present invention relates to a method for producing a heat-resistant SAN resin, a heat-resistant SAN resin and a heat-resistant ABS resin composition, and more particularly to a method for producing a heat-resistant SAN resin by emulsion-polymerizing alpha-methylstyrene and a vinyl cyan monomer. Aggregating the synthesized heat-resistant SAN resin to form an aggregate; And a step of pulverizing the formed aggregate by ultrasonic waves. According to the present invention, a heat-resistant SAN resin in which residual monomer content is greatly reduced by pulverizing aggregates containing residual monomers by ultrasonic waves is manufactured, and the heat-resistant ABS resin produced therefrom has gloss and heat resistance (HDT) has an excellent effect.
