摘要 本文用母函数方法处理了含乙苯的苯乙烯热引发本体聚合系统,建立了分子量分布模型:其中, A differential model for molecular weight distribution (MWD) is presented by using generating functions. An experimental study of thermal bulk polymerization of styrene with 5～25% ethylbenzene in temperature range of 100～170℃ and conversion range of 0～95% is carried out. Conversion, molecular weight distributions are measured. The model parameters are regressed from the experimental data, and are corrected with the conversions. The calculation indicates that the model agrees with experimental data.
