<p>This invention is 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 (-RaSiO(3-a)/2)(F(CF2)b-R<4>-RcSiO(3-c)/2)x(RdSiO(4-d/2) y(R<5>O1/2)z wherein R denotes a monovalent hydrocarbon group free of unsaturated bonding, R<4> denotes an alkylene group or an alkyleneoxyalkylene group, R<5> denotes hydrogen atom 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. These polymers are useful in forming water and oil repellent coatings.</p> |
