| 摘 要： | 由4-[(3,5-二甲基-4-羟基)苯基]-2,3-杂萘-1-酮与4-氯-N-苯基邻苯酰亚胺通过亲核取代反应、水解反应和脱水反应合成了一种新型不对称含二氮杂萘联苯结构的二酐单体,并对其进行结构表征.由新型二酐单体与市售的二胺单体通过“一步法”溶液聚合反应合成了5种含二氮杂萘酮联苯结构的聚醚酰亚胺.通过FTIR和1HNMR方法研究了聚合物的结构及性能.结果表明,该类聚合物既具有较高的耐热性能,又可以在室温下溶解于非质子极性溶剂,如N-甲基吡咯烷酮和间甲酚等.

| Abstract: | A series of novel poly(ether imide)s based on the dianhydride containing 3,5-dimethyl phthalazinone was synthesized and characterized. Poly(ether imide)s with intrinsic viscosities of 0.55-1.88 dL/g[in N-methyl-2-pyrrolidinone (NMP) at 30 ℃] were obtained by one-step solution polymerization in m-cresol. These poly(ether imide)s were readily soluble in some common organic solvents such as N,N-dimethylacetamide and NMP. The poly(ether imide)s derived from 4,4-oxydianiline and 4,4-methylenedianiline were also well soluble in 1,1,2,2-tetrachloroethane and chloroform. Glass transition temperatures determined by differential scanning calorimeter were in the range of 583-628 K. Degradation temperatures for 5% weight loss occurred all above 439 ℃ in nitrogen. |
