Abstract
The present invention relates to silicone and perfluoroalkyl group containing telomers of the formulae ##STR1## wherein R.sub.f 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; R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9 are straight or branched chain alkyl of up to 18 carbon atoms, optionally interrupted by --O--, --S--, --SO.sub.2 -- or substituted by halogen or glycidyl groups; R.sub.10 is hydrogen or lower alkyl; (M.sub.1) represents a monomer unit derived from monomer M.sub.1 which is water soluble with more than 20% solubility in water at 25.degree. C.; (M.sub.2) represents a monomer unit derived from monomer M.sub.2 which is water insoluble with less than 2% solubility in water at 25.degree. 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.
