【摘要】 以新二酸4-[4-(4-羧基苯氧基)苯基]-2-(4-羧基苯基)二氮杂萘-1-酮(1)和4种商品二酚进行溶液缩聚反应,制备出一系列古杂萘联苯结构新型聚芳酯,其特性粘度在0．50-0．58 dL·g-1之间．以FT-IR．1H-NMR证明了聚合物的结构．该类聚芳醇的玻璃化转变温度在209-272℃之间,在N2气氛下10％的热失重温度在468-481℃之间．聚芳本具有无定型结构,可溶解于N-甲基吡咯烷酮(NMP),N,N-二甲基乙酰胺(DMAc),间甲酚,吡啶和氯仿(CHCls)中．扭曲和非共平面的结构存在使该系列聚芳酯既耐高温又具有良好的溶解性能．更多还原

【Abstract】 A series of novel polyarylates were prepared from 40-(4-(4-carboxyphenoxy)phenyl) -2-(4-carboxyphenyl)-2,3-phthalazin-1-one (1) with various bisphenols by solution polycondensation in pyridine at 120℃. These polyarylates were produced with inherent viscosities of 0.50-0.58 dL·g-1. The structure of polymers obtained was confirmed by FT-IR and 1H-NMR. These polyarylates show glass-transition temperatures (T’gs) between 209 and 272℃. The 10% weigh loss temperatures of the polymers, measured by thermogravimetric analysis, were found to be in the range of 468-481℃in nitrogen. These polyarylates are amorphous and most of these polymers exhibit excellent solubility in a variety of solvents such as in N-methyl-2-pyrrolidinone (NMP), N, N-dimethylacetamide (DMAc), m-Cresol, pyridine and chloroform (CHCl3). The results indicate that the aromatic polyesters with the twisted and noncoplanar phthalazinone moieties have good thermal properties and excellent solubility.更多还原
