For the Contracting State : AT 1. Process for the preparation of fluorinated telogens of general formula : Rf-Q-CCl3 in which Rf denotes a linear or branched perfluoroalkyl radical containing from 2 to 20 carbon atoms and Q denotes a linkage group chosen from those of formulae : -(CH2 )r -OCO-(CH2 )S - see diagramm : EP0188952,P25,F1 -(CH2 )r' -COO-(CH2 )s' - see diagramm : EP0188952,P25,F2 or Rf and Q denote together a group of formula : see diagramm : EP0188952,P26,F3 in which : r and s' are integers ranging from 1 to 12, r' and s are integers ranging from 0 to 12, X denotes a hydrogen, chlorine or bromine atom, W denotes a -CH2 -, -CH2 -CCl2 -, -CH2 -CCl2 -CH2 - or -CH2 CCl2 -CF2 - bridge, R denotes a hydrogen atom or an alkyl group containing from 1 to 4 carbon atoms, Y denotes an oxygen or sulphur atom, Z denotes a -CH2 -, -CH2 -C6 H4 - or -COO-(CH2 )t - bridge, t being an integer ranging from 0 to 9, R' denotes a hydrogen atom or a methyl group, W' denotes a direct bond or a -CCl2 -, -CCl2 -CH2 - or -CCl2 -CF2 - bridge, and u is a number ranging from 2 to 100, characterized in that a CCl3 end group is introduced onto a fluorinated compound by : a) esterification of a fluorinated alcohol or acid with, respectively an acid or an alcohol or epoxide cntaining the said CCl3 end group, or b) condensation of a fluorinated carboxylic or sulphonic acid halide with an amine containing the said CCl3 end group, or c) addition to a fluorinated olefin of a haloalkane chosen from carbon tetrachloride, bromotrichloromethane, chloroform, hexachloroethane, pentachloroethane, 1,1,1,3,3,3-hexachloropropane and 2,2-difluoro-1,1,1,3,3,3-hexachloropropane, or d) condensation of a fluorinated alcohol or thiol with the product of addition to chloromethylstyrene of one of the abovementioned haloalkanes.
