AQUEOUS FLUOROPOLYMER EMULSION AND PROCESS FOR PRODUCING THE SAME

摘要

An aqueous fluoropolymer emulsion containing, based on a fluoropolymer, at least 1.5 wt.% of a sodium dialkyl sulfosuccinate and an alkylene glycol. A process for producing a stabilized aqueous fluoropolymer emulsion by mixing a stock solution of an aqueous fluoropolymer emulsion produced by emulsion polymerization with a sodium dialkyl sulfosuccinate dissolved in an alkylene glycol or an aqueous solution thereof. The obtained emulsion is novel and has high mechanical and thermal stabilities.
