Preparation and characterization of soluble copoly(aryl ether ketone)s containing hindering structures: 点击次数：; 发布时间： 2019-03-10; 发布时间：2019-03-10; 论文类型：期刊论文; 发表时间：2000-10-03; 发表刊物：JOURNAL OF APPLIED POLYMER SCIENCE; 收录刊物：EI、SCIE、Scopus; 卷号：78; 期号：1; 页面范围：20-24; ISSN号：0021-8995; 关键字：polycondensation; copoly(aryl ether ketone); chain structure; property; solubility; 摘要：New copoly(aryl ether ketone)s have been synthesized by polycondensation of 2,2',3,3',6,6'-hexaphenyl-4,4'-diphenol, 2,2'-p-hydroxyphenyl-iso-propane, and 4,4'-difluorobenzophenone. The technology of C-13-NMR was used to determine contents of the two bisphenols in the copolymers. Chain structure was characterized by illustrating average block length (L-A, L-C) in terms of portion of the triads (AKA, CKC, AKC). The obtained copoly(aryl ether ketone)s have the properties of excellent solubility, high heat-resistance, good tensile strength, and good selectivity for gas permeability.
