摘　　要：介绍了一种高效甲醛阻聚剂PVFM的主要生产工艺;简述了这种高效阻聚剂的阻聚原理;通过对调聚反应、酸性水解反应的深入分析,指出工艺中采用了复合引发剂BPO、H2O2,并提出了由BPO引发反应温度上限的设计依据;分析了工艺中各主、副化学反应的机理;阐述了PVFM分子聚合度、分子量、多种调聚基团的工艺控制途径;推测PVFM分子的一种可能结构;提出将有益副反应提升至主反应的工艺设计思路。The main production process and polymerization in- hibition principle of PVFM,a kind of high efficient formalde- hyde inhibitor,has been briefly introduced. Based on the anal- ysis of telomerization and acidolysis reaction,the design basis of BPO initiation reaction temperature limit was obtained and. BPO, H2 02 were used as the composite initiator in the process also put forward The mechanism of main and side reactions in the process is analyzed. The process control approach of poly- merization degree,molecular weight and telomerization groups is expounded. A possible molecular structure of PVFM is speculated. The process design idea to enhance the beneficial side reaction to the main reaction is proposed.
