ABSTRACT:
Process for the production of PCTFE homopolymer and/or copolymer resins by the use of an aqueous suspension 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 PCTFE homopolymer or copolymer resin having a desired target range of molecular weights. The process provides stable PCTFE polymer suspensions which exhibit a low tendency to coagulate and further exhibit good wettability of the homopolymer and copolymer particles, notably in the absence of soaps.
