ABSTRACT:
The present invention provides a method of preparing an aqueous dispersion of poly(perfluorovinyl ether) homopolymers. The present invention further relates to a method of making an aqueous fluoropolymer dispersion comprising bicomponent particles of poly(perfluorovinyl ether) homopolymers and a second fluoropolymer. The dispersions of the present invention may be used for rendering fibrous substrates oil repellent, water repellent and/or stain repellent without altering the looks and feel of the substrate.
