摘要：

The synthesis of polystyrene plays an important role in the macromolecule industry. In this article, AIBN、BPO and dl-Diethyl-2,3-Dicyano-2,3-Diphenylsuccinate(Ⅰ) were chosen as initiators of styrene. From the curve of conversion(α) and time(t) (chart omitted), we can get the decomposition velocity constant (kd)、the decomposition activation energy (Ed) of these initiators and the final conversion(α∞) of styrene.(Table 1).
