摘要： 制备了对叔丁基杯[4]芳烃和聚丙烯共混体系,用热重法研究了对叔丁基杯[4]芳烃对聚丙烯热氧稳定性的影响.用Coats-Redfern方程进行动力学处理,确定对叔丁基杯[4]芳烃和聚丙烯共混体系的热氧降解的表观反应级数为1.413,表观活化能为154.899kJ/mol.

Abstract: The p-tert-butyl calix[4]arene and polypropylene blend was prepared, and effects of p-tert-butyl-calix[4]arene on the thermal oxidation stability of polypropylene blend were studied by means of thermal gravimetric analysis (TGA).Treated with Coasts-Redfern equation we found that the apparent degradation reaction order of the p-tert-butyl-calix[4]arene and polypropylene blend is 1.413 and the activation energy of degradation reaction is 154.899 kJ/mol.
