Synthesis and thermal properties of emulsion terpolymers of N-p-tolylmaleimide/butadiene–styrene latex/AN/St

摘要

Heat-resistance ABS resin was synthesized by emulsion polymerization of N-p-tolylmaleimide (N-PTMI), butadiene–styrene latex (SB), AN and St. Thermal properties of terpolymers with different monomer ratio were characterized by DSC and TG. The molecular mass and molecular mass distribution of terpolymers were determined with GPC. The results shown the heat-resistance of terpolymers, the glass transition temperature and the decomposition temperature were increased with the increasing of N-PTMI feed content. With the increasing of AN feed content, the glass transition temperature of terpolymers decrease while the decomposition temperature increase. The glass transition temperature of terpolymers decrease with SB feed content and the product shows plastic properties when SB feed content is lower than 45 (m/m %).
