Abstract
A process of preparing a copolymer of vinyl monomer such as vinyl acetate, vinyl propionate and vinyl trifluoroacetate, and of fluorinated monomers such as tetrafluoroethylene and trifluoroethylene, said copolymer having an alternating or substantially alternating distribution of vinyl recurring monomeric units and fluorinated recurring monomeric units in the copolymer backbone which comprises copolymerizing said monomers in an aqueous reaction medium comprising water and a water miscible organic co-solvent in an amount less than the amount sufficient to form a distinct organic co-solvent phase.
