Abstract
Abstract: Copolymers of N-p-tolylmaleimide, methyl methacrylate, and acrylonitrile were synthesized by the method of semibatch emulsion polymerization and used for blending with poly(vinyl chloride) (PVC) to improve its heat resistance. The thermal properties of the blends with different terpolymer content were investigated by differential scanning calorimeter (DSC), thermogravimetric analysis (TGA), and Vicat softening point tester (TVicat). The results showed that the glass transition temperature (Tg), Vicat softening point, and thermal decomposition temperature of the blends increased with increasing terpolymer content. The tensile strength increased with an increasing in the copolymer content. The results of the rheological behavior showed that the apparent viscosity ŋα decreased with increasing shear rate and increased with the copolymer content.
