ABSTRACT:
The present invention provides a method of making a fluoropolymer comprising repeating units derived from one or more gaseous fluorinated monomers. The method comprises an aqueous emulsion polymerization of gaseous fluorinated monomers in the presence of an ether selected from the group consisting of dimethyl ether (DME), methyl tertiary butyl ether (MTBE) and mixtures thereof.
