Abstract: This invention relates to a silicone-modified vinyl polymer having a weight-average molecular weight from 1,000 to 1,000,000 containing a siloxane group having the formula(--R.sub.a SiO.sub.(3-a)/2)(F(CF.sub.2).sub.b --R.sup.4 --R.sub.c SiO.sub.3-c)/2).sub.x (R.sub.d SiO.sub.(4-d)/2).sub.y (R.sup.5 O.sub.1/2).sub.zwherein R denotes a monovalent hydrocarbon group free of unsaturated bonding, R.sup.4 denotes an alkylene group or an alkyleneoxyalkylene group, R.sup.5 denotes hydrogen or an alkyl group, a is an integer from 0 to 2, b is an integer with a value of at least 4, c is an integer from 0 to 2, d is an integer from 0 to 3, x is a number greater than 0, and y and z are each numbers with values of 0 or more. The polymers of this invention are useful in forming water repellent and oil repellent coatings.
