Novel high-efficiency polyvinyl chloride synthetic chain transfer agent

A few days ago, under the joint efforts of the Shanghai Reagent Research Institute and the Shanghai Chlor-Alkali Chemical Co., Ltd. Technical Center, a new type of highly effective PVC synthesis chain transfer agent, 1-chloro-1-iodoupane, was successfully researched. 1-Chloro-1-iodoalkane is the best chain transfer agent for PVC synthesis in the world. If it is used in place of mercaptoethanol, it is widely used in the PVC industry. It can not only shorten the polymerization time of vinyl chloride, but also greatly reduce the initiation of polymerization. Dosage, but also has obvious advantages in reducing the quality of PVC products, reducing production costs.
