Abstract: Based on the property of intrinsic viscosity of intra - crosslinking polymer, a new method to determine the rate constant of the primary intra - crosslinking reaction was developed in the crosslinking copolymerization. Furthrmore, the method was testified in the copolymerization system of vinyl chloride/diallyl phathalate.
摘要: <正>悬挂双键行为是自由基交联共聚反应的关键,除参与分子间交联反应外,还可参与环化、初级分子内交联、次级分子内交联等反应。环化反应定义为二(多)烯自由基“回咬”同一单体链节中的悬挂双键的反应,初级分子内交联反应指自由基“回咬”同一基链上的悬挂双键的反应,次级分子内交联反应指自由基“回咬”同一分子中其它基链上的悬挂双键的反应。 由于二烯用量极少。通常很难定量测定悬挂双键浓度。很少有定量研究悬挂双键行为的实验报道,Lantin用超导核磁共振仪直接测定了甲基丙烯酸甲酯-乙二醇二甲基丙烯酸酯体
