摘要
采用悬浮聚合法合成了Ｎ－苯基马来酰亚胺（ＮＰＭＩ）－苯乙烯（Ｓｔ）－丙烯腈（ＡＮ）三元共聚物，并用元素分析、ＤＳＣ、ＴＧＡ等手段进行了表征。结果表明：该三元共聚物具有好的耐热性能，玻璃化温度和热稳定性随共聚物中ＮＰＭＩ含量的增加而提高，将是一种具有广阔开发前景的耐热改性剂。
Poly (Nphenyl maleimidestyreneacrylonitrile) was synthesized by using a suspension method.The characterization of the copolymers was measured by element analysis,and by means of DSC,TGA.It is found that poly (NPMIStAN) exhibits excellent thermal stability.Its glass transition temperature and extrapolated onset temperature tend to increase as the NPMI content of copolymer increases.
