摘要: 本文考察了转化率、聚合温度和链转移剂对聚氯乙烯平均分子量的影响,并建立了分子量调节模型,定义了一拟链转移常数.这一模型可用于预测加有链转移剂时的聚氯乙烯平均分子量.

Abstract: This paper studies the effects of conversion, polymerization temperature, nature and concentration of chain transfer agents on the average molecular weight of poly (vinyl chloride), and proposes a regulation model of the average molecular weight of PVC. The model may be used to estimate the average molecular weight of PVC in the polymerization process with mercaptoethanol or trichloroethylene as chain transfer agent.
