主链含酰亚胺结构的聚醚醚酮的合成及其性能
摘要:
以1,4-二苯氧基苯为单体分别与N,N'-(4,4'-二苯甲烷)-双-(3,4-二甲酰亚胺基苯甲酰氯)和N,N'-(4,4'-二苯砜)-双-(3,4-二甲酰亚胺基苯甲酰氯),采用低温溶液缩聚合成了2种主链含酰亚胺结构的聚醚醚酮树脂,聚合物的比浓对数粘度分别为0.98和0.61 dL/g。用FT-IR、1H NMR和WAXD进行了结构表征,用DSC和TGA测试了热性能。结果表明,聚合物有较高的玻璃化转变温度(Tg分别为236和263℃),N2气气氛中热分解温度(5%Td)分别为529和512℃,能溶于N,N-二甲基乙酰胺、N-甲基-2-吡咯烷酮、氯仿和间甲酚等常见的有机溶剂中。

Synthesis and Properties of Poly(ether ether ketone) Containing Imide Moiety
Abstract:
Two novel poly(ether ether ketone)s(PEEK) containing imide moiety with inherent viscosities of 0.98 dL/g and 0.61 dL/g were respectively prepared by low temperature solution polycondensation from 1,4-diphenylbenzene(DPB) with N,N'-(4,4'-diphenylmethane) bistrimelletimide diacid chloride(DCDI-M) or N,N'-(4,4'-diphenylsulfone) bistrimelletimide diacid chloride(DCDI-S).The polymers were characterized by FT-IR,1H NMR,DSC,TGA and WAXD.The results show that the polymers are amorphous.The glass transition temperatures(Tg) are 236 ℃ and 263 ℃,respectively.The onset temperatures taken at a 5% mass loss of each of the polymers in nitrogen atmosphere are all over 512 ℃.The polymers are soluble in common organic solvents such as N,N-dimethylacetamide(DMAc),N-methylpyrrolidone(NMP),cresol and chloroform at room temperature.
