    摘要: The present invention relates to telomers of 1,2-dichloro-­1,2-difluoroethylene and to a process of preparing them.
    1,2-dichloro-1,2-difluoroethylene is reacted, at a temperature of from -100°C to +50°C, with a perhalofluorooxy compound of formula
    R x -OF
    wherein
    R x represents, among other, a perhaloalkyl radical of from 1 to 10 carbon atoms.
    Telomers are obtained which have, among others, the formulae
    R X O-(CFCl) n -F
    R x O-(CFCl) n -OR x
    R y -(CFCl) n -F and
    F-(CFCl) n -F,
    wherein
    R y represents, among others, a perhaloalkyl radical containing from 1 to 9 carbon atoms.
    Most of the resulting telomers are new products.
