Abstract

Poly(N-(3-carboxyphenyl)maleimide-alt-styrene) with superior heat-resistance was synthesized by free radical copolymerization and its structure was confirmed by FTIR and NMR spectroscopy. To show the advantages in heat-resistance of the synthesized copolymers, the thermal properties of poly(N-phenylmaleimide-alt-styrene) and poly(N-phenylmaleimide-alt-maleic anhydride) with similar structures were determined. DSC/TG analysis showed that the synthesized copolymer exhibited the better thermal properties than two other copolymers due to the formation of a chemically crosslinked three-dimensional network during heating.

功能化聚（N-（3-羧基苯基）马来酰亚胺-alt-苯乙烯）的合成及其耐热机理

摘要

聚（ñ - （3-羧基苯基）马来酰亚胺ALT -苯乙烯）具有优异的耐热性，通过自由基共聚合成，其结构通过FTIR和NMR光谱证实。要显示在合成的共聚物的耐热性等优点，聚（的热性能Ñ -phenylmaleimide- ALT -苯乙烯）和聚（Ñ -phenylmaleimide- ALT -马来酸酐）与类似的结构进行了测定。DSC / TG分析表明，由于在加热过程中形成了化学交联的三维网络，因此合成的共聚物表现出比其他两种共聚物更好的热性能。
