Silicone resin, manufacture of the same and dental adhesive comprising the same

Abstract

Abstract PURPOSE:To provide a silicone resin which exhibits excellent adhesion when used as an adhesive between a silicone rubber backing material and an artificial tooth bed, is excellent in water resistance, and can be used in the mouth for a long period of time, by using a copolymer comprising a combination of specific repeating units. CONSTITUTION:The title silicone resin is a copolymer comprising repeating units of formula I, II, III and IV, the combination being any of (a), (b) or (c) given below, wherein the repeating units are bonded in an arbitrary order with the numbers being arbitrary: (a) formulae I and IV, (b) formulae II and IV and (c) formulae of III and IV. In formulae I-IV, R<1> and R<7> may be the same or different and each is hydrogen or a lower alkyl group; R<2>, R<3>, R<4> and R<8> may be the same or different and each is a lower group; R<5> and R<6> may be the same or different and each is a lower alkyl group or a vinyl group; and T<1> and T<2> may be the same or different and each is a lower alkylene group.
