    摘要: UV-crosslinkable acrylic hotmelt pressure sensitive adhesives comprising acrylic and vinyl monomers, and a polymerizable UV photoinitiator. The photoinitiator comprises a spacer comprising both ethylene oxide and urethane, or urea, carbonate, or siloxane functional groups. The ethylene oxide is directly bonded to the chromophore (e.g., benzophenone) moiety, while the urethane (or urea, carbonate, siloxane) is closely linked to the polymerizable moiety (e.g., styrenic C═C double bond).

    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.
