摘要： 合成了含活性侧基的苯乙烯/N-对羟苯基马来酰亚胺共聚物(SHMI),使某些具有特定功能的有机小分子接枝到聚合物主链上.用FTIR,NMR及GPC研究了其化学结构,并用DSC和TGA研究了其热转变和热降解性能.结果表明,SHMI是交替共聚物,其玻璃化转变温度(Tg)高达526K,于661K开始降解,降解动力学遵循Arrhenius方程,有良好的溶解成膜性能.

Abstract: Styrene/N-(4-hydroxyphenyl) maleimide copolymer(SHMI), which has an active side-group and can be reacted with other organic molecules with special optical and electrical properties, were synthesized. SHMI can be used as backbone for functional and special polymers. The structures of SHMI products were studied by FTIR, NMR and GPC. DSC and TGA were employed to study the thermal transition and thermal degradation of SHMI. It is shown that SHMI is an alternating copolymer with high glass transition temperature(Tg =526 K), good solubility and film-forming properties. The thermal degradation kinetics of SHMI can be fitted by Arrhenius equation. The initial thermal degradation temperature(Td1) of SHMI is 661 K.

Key words: N-(4-Hydroxyphenyl) maleimide, Styrene/maleimide copolymer, Active side-group, Thermal stability
