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 Rx-OF wherein Rx represents, among other, a perhaloalkyl radical of from 1 to 10 carbon atoms. Telomers are obtained which have, among others, the formulae RXO-(CFCl)n-F RxO-(CFCl)n-ORx Ry-(CFCl)n-F and F-(CFCl)n-F, wherein Ry represents, among others, a perhaloalkyl radical containing from 1 to 9 carbon atoms. Most of the resulting telomers are new products

Abstract
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 Rx-OF wherein Rx represents, among other, a perhaloalkyl radical of from 1 to 10 carbon atoms. Telomers are obtained which have, among others, the formulae RXO-(CFCl)n-F RxO-(CFCl)n-ORx Ry-(CFCl)n-F and F-(CFCl)n-F, wherein Ry represents, among others, a perhaloalkyl radical containing from 1 to 9 carbon atoms. Most of the resulting telomers are new products
