摘　　要：采用种子滴加法合成了苯乙烯与N-间甲苯基马来酰亚胺共聚物乳液,讨论了单体配比对乳液的聚合稳定性、表面张力、流变性、粒径大小及分布、成膜性能的影响。并用DSC和TGA对共聚物耐热性能进行了表征。实验结果表明,随着N-间甲苯基马来酰亚胺含量的增加共聚物的Tg呈明显上升趋势。NMTMI/St copolymer by emulsion polymerization was studied. It has been found that monomer composition ratio has influenced on the polymerization stability, interracial tension , latex viscosity,mean partice diameter of latex , particles surface morphology. The themal properties of the copolymer were synthesized by differential scanning calorimetry and thermogravimetric analysis. The result shows that Tg increases with the increasing NMTMI content.
