    摘要: This invention provides fluorine-containing polymers having a plurality of thioorgano groups. These polymers are prepared by reacting a fluoropolymer precursor with one or more, organic, thiolate compounds thereby modifying the fluoropolymer precursor by grafting onto its backbone the thioorgano groups. Said thioorgano groups may contain functional moieties that modify the cure properties, bulk properties or compatibility of the thioorgano fluoropolymer precursor. This invention also provides shaped or formed cured articles, coatings and solutions comprising the thioorgano fluoropolymers, and blends thereof with other compatible polymers.
