    • A living polymerization process for preparation of poly(vinyl chloride) (PVC) with controlled molecular weight and molecular weight distribution is described. The polymerization reaction can be initiated by various polyhalocarbon initiators in conjunction with non-metallic reducing single electron transfer reagents as catalysts and accelerated by electron shuttles. The process occurs at room temperature in water or water-organic solvent medium. The polymerization provides PVC with a controlled molecular weight and narrow molecular weight distribution. The halogen containing polymer compositions are useful as, among others, viscosity modifiers, impact modifiers and compatibilizers.
    • 描述了具有受控分子量和分子量分布的聚(氯乙烯)(PVC)的制备活性聚合方法。 聚合反应可以通过各种多卤代烃引发剂与非金属还原性单电子转移试剂结合起来,作为催化剂并通过电子穿梭加速。 该方法在室温下在水或水 - 有机溶剂介质中进行。 聚合提供具有受控分子量和窄分子量分布的PVC。 含卤素的聚合物组合物可用作粘度改进剂,抗冲改性剂和增容剂等。
