Fluoropolymer Dispersion Treatment Employing Oxidizing Agent to Reduce Fluoropolymer Resin Discoloration

摘要

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