PRODUCTION OF FLUOROPOLYMERS, FLUOROPOLYMER SUSPENSION AND POLYMER FORMED THEREFROM

摘要

Process for the production of fluoropolymers and/or copolymer resins thereof by the use of an aqueous dispersion system incorporating a redox initiator system which comprises t-butyl hydroperoxide and sodium metabisulfite to initiate the polymerization or copolymerization process. The process parameters may be controlled to provide a fluoropolymer or copolymer resin thereof having a desired target range of molecular weights. The process provides stable fluoropolymer dispersions which exhibit a low tendency to coagulate and further exhibit good wettability of the fluoro-homopolymer and copolymer particles, notably in the absence of soaps.
