Claims
- 1. A composition consisting essentially of
- (A) 100 parts by weight partially oxidized tributyl boron,
- (B) 10 to 150 parts by weight acetone, and
- (C) 5 to 100 parts by weight a liquid or solid co-oligomer or copolymer of methyl methacrylate and (iso)butyl methacrylate, and which is inert to the partially oxidized tributyl boron.
- 2. A dental or surgical adhesive composition obtained by mixing 30 to 90 parts by weight of (a) a polymerizable monomer, (b) 0 to 60 parts by weight of (b) (meth)acrylate polymer, and 1 to 30 parts by weight of (c) a separately prepared polymerization initiator composition based on 100 parts by weight of the total of the components (a), (b) and (c), wherein the separately prepared polymerization initiator consists essentially of
- (A) 100 parts by weight of an organic boron compound;
- (B) 10 to 150 parts by weight of an aprotic solvent having a boiling point of 30 to 150.degree. C.; and
- (C) 5 to 100 parts by weight of a liquid or solid organic oligomer or polymer, which is inert to said organic boron compound;
- wherein the organic boron compound is partially oxidized tributyl boron, the aprotic solvent is acetone, and the organic oligomer or polymer (C) is a co-oligomer or copolymer of methyl methacrylate and (iso)butyl methacrylate.
