Fluorination of Fluoropolymer Resin to Reduce Discoloration

摘要

Process for reducing thermally induced discoloration of fluoropolymer resin produced by polymerizing fluoromonomer in an aqueous medium to form aqueous fluoropolymer dispersion and isolating said fluoropolymer from said aqueous medium to obtain said fluoropolymer resin. The process comprises: exposing the fluoropolymer resin to fluorine.
