    摘要: The reactive injection molding of a urethane-based resin composition according to the invention is performed by admixing the polyol compound as one of the reactants of the urethane-based resin with a specific organopolysiloxane as an internal mold release agent so that the molding process can be performed without application of an external mold release agent to the metal mold. The organopolysiloxane is characterized by two types of substituent groups bonded to the silicon atoms, of which the first type is --C.sub.x H.sub.2x OR', R' being a monovalent hydrocarbon group of 8 to 30 carbon atoms free from chain end unsaturation and x being 0-4, and the second type is --C.sub.y H.sub.2y (OC.sub.n H.sub.2n).sub.m OH, y being 1-4, n being 2-4 and m being 0-45.

    摘要: The invention provides an organopolysiloxane having at least one polyhydric pendant group bonded to the silicon atom as derived from a polyglycerol compound. Such an organopolysiloxane is useful as a non-ionic surface active agent. The organopolysiloxane can be prepared by the hydrosilation reaction between an organohydrogenpolysiloxane having at least one hydrogen atom directly bonded to the silicon atom and a polyglycerol compound having an aliphatically unsaturated linkage in the molecule such as those obtained by the reaction of allyl alcohol and glycidol or by the reaction of diglycerin and allyl glycidyl ether.
