Novel organopolysiloxanes have the average compositional formula (1): <IMAGE> (1) wherein X is a monovalent substituent containing a polyoxyethylene group, Y is a 3-(meth)acryloxypropyl group, R1 is a C1-6 alkyl group or phenyl group, a=0 or 1, 1</=b</=20, 0</=c</=10, 1</=d</=10, and 1</=a+c</=10. They are prepared by effecting addition reaction of an aliphatic unsaturated compound containing a polyoxyethylene group to corresponding organohydrogenpolysiloxanes. |
