In this paper, the polymerization rate and average molecular weight of thermal-initiated polymerization of styrene in the range of 120~ 200C were studied. The polymerization rate was found to be proportional to the square of styrene concentration, thus a second-order initiation is inferred.

在120~200℃内,对热引发苯乙烯本体聚合的速率及平均分子量进行了研究,得到聚合速率与单体浓度二次幂有关,据此可以推论引发速率也和单体二次幂有关。
