摘要： A novel silicone-acrylic copolymer which comprises a covalently bonded silicone polymer with an acrylic polymer through the -Si-O-Si- linkage is described. The silicone-acrylic copolymer is a reaction product of (a) a silicone polymer, (bi) a mixture of acrylic monomers wherein at least one acrylic monomer comprises a silane (meth)acrylic monomer and/or a siloxane (meth)acrylic macromer with a radical initiator to form an acrylic prepolymer or (bii) an acrylic polymer which comprises a silane or a siloxane functional group; and (c) a scrambling catalyst, wherein the ratio of the silicone polymer (a) and the mixture of acrylic monomers (bi) or polymer (bii) is from 50:1 to 1:50. The silicone-acrylic copolymer is useful as an adhesive, sealant, coating, and the like.

摘要： The present invention relates to a ultra-violet curable pressure sensitive adhesive comprising an acrylic polymer and a cationic photoinitiator, wherein said acrylic polymer comprises: (i) an acrylic monomer consisting of an acrylic or methacrylic acid derivative of the formula CH 2 =CH(R 1 )(COOR 2 ), wherein R 1 is H or CH 3 and R 2 is C 1-20 alkyl chain; (ii) a monomer, wherein the monomer (a) comprises a pendant reactive functional groups selected from both (1) cycloaliphatic epoxide, oxetane, benzophenone or mixtures thereof, and (2) monosubstituted oxirane, and (b) wherein said monomer contains from 0.001 to 0.015 equivalent per 100g of said acrylic polymer; and said acrylic polymer is free of multi-(meth)acrylate.
