摘要： An ultraviolet-curable silicone composition for a release paper including (A) 100 parts by mass of a specific organopolysiloxane having a polymerization degree of 8 to 20 and containing one epoxy group, and (C) an effective quantity of an onium salt photoinitiator. In a preferred embodiment, the composition further includes (B) 10 to 1,000 parts by mass of at least one specific organopolysiloxane containing a plurality of epoxy groups. In another preferred embodiment, the composition has a viscosity of not more than 100 mPa·s. The composition has a peel strength that exhibits a positive dependency on the peel speed when peeled from a hot-melt pressure-sensitive adhesive, and can therefore be used to produce a release paper capable of reducing peeling noise. Further, because the composition has a low viscosity, it exhibits excellent wetting of substrates having significant unevenness, even in a solventless form.

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.
