Abstract: By using Friedel-Crafts catalyst a family of soluble and fusible polymers has been synthesized by polycondensation of an aralkyl ether, such as p-di (methoxy)-xylene or 4,4/-di(methoxymethyl) diphenyl ether with any of ten kinds of aromatics such as phenol, cresol, or phenyl ether. Their average molecular weight is about 2000 and their chemical and physical structures have been determined. When cross-linked, these polymers have a good thermal stability. Their pyrolysis temperatures are over 400℃ with activation energies around 100 kJ/mol.

摘要： 本文以两种芳烷基醚与十种芳香族化合物,分别在Freidel-Crafts型催化剂作用下进行缩聚反应,得到一系列的可溶可熔、分子量为2000左右的聚合物.该聚合物经交联后具有良好的热稳定性,热分解温度均大于400℃,热分解活化能均在100kJ/mol左右.
