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。

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.

Key words: imide moiety,diphenoxylbenzene,poly(ether ether ketone)
