Abstract: Terpolymers of N-p-tolylmaleimide(NPTMI), methyl methacrylate(MMA) and acrylonitrile(AN) were synthesized by emulsion polymerization. The thermal properties of the terpolymers were investigated by torsional braid analysis, differential scanning calorimetry, thermogravimetric analysis and vicat softening point tester. The results showed that the glass transition temperature(Tg) and vicat softening point of the terpolymers increased with the increase of NPTMI content but decreased with the increase of AN content. The initial decomposition temperature(T0) and the half weight-loss temperature(T50) increased both with increasing NPTMI and AN content. The weight and number average molecular weights were also determined by gel permeation chromatography. The results showed that there was a maximum value at mass ratio 10∶85∶5 of NPTMI/MMA/AN.
