降冰片烯与N-环己基马来酰亚胺共聚物的合成

Synthesis of Norbornene-N-cyclohexylmaleimide Copolymers

以偶氮二异丁腈 (AIBN)为自由基引发剂 ,以降冰片烯 (NBE)、N 环己基马来酰亚胺(CHMI)、马来酸酐 (MA)和环己胺 (CHA)为主要原料 ,分别利用降冰片烯、N 环己基马来酰亚胺单体自由基共聚合 ,降冰片烯和马来酸酐共聚物的官能团酰亚胺化反应合成降冰片烯和N 环己基马来酰亚胺的共聚物 .并利用红外光谱对两种方法合成的聚合产物结构进行了表征 ,同时考察了降冰片烯和N 环己基马来酰亚胺共聚物的分子量及分子量分布情况 .

Norbornene, N cyclohexylmaleimide,maleic anhydride and cyclohexylamine were used as main materials to copolymerize Norbornene N cyclohexylmaleimide copolymers by two methods. One was free radical induced copolymerization of norbornene and N cyclohexylmaleimide, the other was P(NBE/MA) functional group imidization. The structures, molecular weights, and molecular weight distributions of the synthesized copolymers were evaluated using IR spectra and gel permeation chromatography.
