The present invention relates to silicone and perfluoroalkyl group containing telomers of the formulae <IMAGE> I. and <IMAGE> II. wherein Rf is a straight or branched chain perfluoroalkyl up to 18 carbon atoms or said perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms, or mixtures thereof; W and E are divalent linking groups; R1, R2, R3, R4, R5, R6, R7, R8, and R9 are straight or branched chain alkyl of up to 18 carbon atoms, optionally interrupted by -O-, -S-, -SO2- or substituted by halogen or glycidyl groups; R10 is hydrogen or lower alkyl; (M1) represents a monomer unit derived from monomer M1 which is water soluble with more than 20% solubility in water at 25 DEG C.; (M2) represents a monomer unit derived from monomer M2 which is water insoluble with less than 2% solubility in water at 25 DEG C.; x and z are integers from 10 to 500; y is an integer from 1 to 25; p is an integer from 1 to 500 and q and r are integers from 0 to 250. These compositions are useful as coatings on glass, paper, wood, leather and especially textiles.
