摘要： 光学活性聚甲基丙烯酸三苯甲酯是单手螺旋链构象的聚合物,其链构象具有较高的热稳定性。这样一个手性螺旋链聚合物的热学行为是人们所关心的。本实验室合成了光学活性聚甲基丙烯酸三苯甲酯(PTrMA),聚甲基丙烯酸邻甲基苯基二苯甲酯(o-PDPTMA),聚甲基丙烯酸邻甲氧基苯基二苯甲酯(PMTrMA)和聚甲基丙烯酸对甲基苯基二苯甲酯(p-PDPTMA)。

Abstract: Optically active polymer series of poly(triphenylmethy methacrylate) has been studied by thermogravimetry. The effects of heating rate and surrounding atmosphere on the thermal behaviour of polymers are discussed. The activation energy of thermal degradation of PTrMA is calculated by the differential and integral methods. The thermal stability and mechanism of thermal degradation has been discussed.

Key words: triphenylmethyl methacrylate polymer, optical active polymer, thermal property
