ABSTRACT:
Production of an aqueous-based composition comprising a fluoropolymer and a vinyl copolymer by (1) preparing a non-aqueous solution of a fluoropolymer comprising repeat units derived from at least one fluorolefine and repeat units bearing chain-pendant disperser groups imparting water-emulsifiability or water-solubility to the fluoropolymer; (2) converting the non-aqueous solution formed in step (1) into an aqueous-based emulsion or solution of said fluoropolymer; and (3) polymerising at least one vinyl monomer to form a vinyl polymer in the presence of said aqueous-based emulsion or solution from step (2).
