摘要
聚醚醚酮(PEEK)是一种新型耐高温工程塑料。本文以K_2CO_3和K_2CO_3/Na_2CO_3混盐为成盐剂合成了PEEK,经过系统地表征和光谱的研究发现:前者存在少量支化结构,色泽不好,溶解性差;后者是全对位结构,色泽好,溶解性好。
PEEK is a high-temperature engineering plastic. In this paper, PEEK were prepared by different salting ways.The results suggest that there is a little branch point in the structure when K2CO3 is used in the polycondensition of PEEK, but there is a all-para structure when the mixture of K2CO3 and Na2CO3.
