The substitution of polychlorotrifluoroethylene with sulfur,selenium, and phosphorus nucleophiles

The substitution of polychlorotrifluoroethylene (PCTFE) with sulfur, selenium, and phosphorus nucleophiles is reported. The primary reaction, which extends throughout the bulk of the polymer, is the incorporation of the nucleophile with concommitant loss of chloride. The substituted PCTFE's are studied by ¹H-, ¹³C-, ¹⁹F-, and ³¹P-NMR, as well as IR, and elemental analysis.
