Abstract
Novel organopolysiloxanes have the average compositional formula (1): ##STR1## wherein X is a monovalent substituent containing a polyoxyethylene group, Y is a 3-(meth)acryloxypropyl group, R.sup.1 is a C.sub.1-6 alkyl group or phenyl group, a=0 or 1, 1.ltoreq.b.ltoreq.20, 0.ltoreq.c.ltoreq.10, 1.ltoreq.d.ltoreq.10, and 1.ltoreq.a+c.ltoreq.10. They are prepared by effecting addition reaction of an aliphatic unsaturated compound containing a polyoxyethylene group to corresponding organohydrogenpolysiloxanes.
