IODONITRILES AS CHAIN TRANSFER AGENTS IN THE MANUFACTURE OF PERFLUOROPOLYMERS

摘要

Iodoperfluoroalkylnitriles are useful as chain transfer agents in the free radical polymerization of vinyl monomers to form perfluoropolymers. These nitriles provide end groups which may take part in a cross-linking reaction, if desired, and also have a relatively low toxicity. The resulting perfluoropolymers are useful as molding resins and elastomers, particularly for parts where good chemical resistance and/or high temperature resistance are desirable.
