Synthesis of new soluble aromatic poly(amide imide)s from unsymmetrical extended diamine containing phthalazinone moiety: 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：2004-05-05; 发表刊物：JOURNAL OF APPLIED POLYMER SCIENCE; 收录刊物：EI、SCIE、Scopus; 卷号：92; 期号：3; 页面范围：1516-1520; ISSN号：0021-8995; 关键字：poly(arylene amide imide)s; heterocyclic polymer; high-performance polymer; polycondensation phthalazinone; 摘要：The preparation of a new unsymmetrical kink non-coplanar heterocyclic diamine, 1,2-dihydro-2-(4-aminophenyl)-4-[4-(3-phenyl-4-aminophenoxy)phenyl]- (2H)phthalazin-l-one (3), from a readily available unsymmetrical phthalazinone bisphenol-like (1) was described. The diamine can be directly polymerized with various aromatic bis(trimellitimide)s (4a-e) by using triphenyl phosphite and pyridine as condensing agents to give a series of new aromatic poly(amide imides) (5a-e) containing the kink non-coplanar phthalazinone heterocyclic units with inherent viscosities of 0.57-1.06 dL/g. The polymers were readily soluble in a variety of solvents such as N,N-dimethylform- amide, N,N-dimethylacetamide, dimethylsulfoxide, N-methyl-2-pyrrolidinone, and even in pyridine and m-cresol and could be cast to form flexible and tough films. The glass transition temperatures were in the range of 315-340degreesC, and the temperatures for 5% weight loss in nitrogen were in the range of 487-512degreesC. (C) 2004 Wiley Periodicals, Inc.
