摘要： A novel method is disclosed for the preparation of a (meth)acryloxyalkyl group-containing organopolysiloxane having a linear structure by the ring-opening siloxane rearrangement polymerization reaction of a (meth)acryloxyalkyl group-containing cyclic organopolysiloxane oligomer either alone or in combination with a cyclic organopolysiloxane oligomer having no (meth)acryloxyalkyl groups. Different from conventional acidic catalyst, the reaction can be promoted by the use of a cation-exchange resin in the H.sup.+ form which can be readily removed from the polymerization mixture after completion of the polymerization reaction leaving no acidic matter which influences on the stability of the product. The catalytic efficiency of the cation-exchange resin can be further enhanced when the resin is, prior to contacting with the cyclic organopolysiloxane oligomer(s), impregnated or swollen with a polar organic solvent such as tetrahydrofuran.

摘要： Proposed is an improved radiation-curable organopolysiloxane composition capable of giving a cured surface film on a substrate surface which exhibits excellent releasability against sticky substances. The composition is obtained by combining two kinds of (meth)acryloxyalkyl-containing organopolysiloxanes in a specified weight proportion, of which one has a relatively large degree of polymerization but contains only a relatively small amount of the silicon-bonded (meth)acryloxyalkyl groups while the other has a relatively small degree of polymerization but contains a relatively large amount of the silicon-bonded (meth)acryloxyalkyl groups. By virtue of this unique formulation, the surface-release sheet provided with a cured surface film of this organopolysiloxane composition and attached to a sticky surface for temporary protection is safe from generation of a peeling noise which is unavoidable in the prior art when a surface-release sheet is peeled off from the sticky surface at a high peeling velocity, especially, when the peeling resistance is great.

摘要： A novel organopolysiloxane compound is proposed which has, in a molecule, at least three (meth)acryloxy groups localized at only one of the molecular chain ends of the polysiloxane chain. By virtue of the localization of the (meth)acryloxy groups, the organopolysiloxane compound is highly curable by the irradiation with a radiation, e.g., electron beams and ultraviolet light, to give a cured coating film on a substrate surface exhibiting excellent releasability against sticky substances. A synthetic route for the preparation of such a one-end crosslinkable organopolysiloxane compound is described.

It further contains an acid, acid generator, base or base generator or an oniom salt photo-initiator as a curing agent. The cured product has release property from adhesive substance which remains unchanged with the lapse of time and good mold release properties, and thus provides a lightly releasable cured film. The composition is widely used as adhesive tape backing agents, mold release agents, protective coating agents, water and oil repellent agents, and paint base.
