Abstract
Abstract An adhesive composition comprises a redox system comprising a reducing agent and an oxidizing system comprising A. 5 to 30 wt. parts of an elastomer of a copolymer of butadiene and acrylonitrile or a copolymer of butadiene and acrylonitrile and less than 5 wt.% of a functional monomer or a graft copolymer of butadiene and at least one of acrylonitrile, styrene and methacrylic acid ester and B. 70 to 95 wt. parts of a monomer mixture comprising 30 to 80 wt.% of 2-hydroxy ethyl methacrylate or 2-hydroxy propyl methacrylate and 20 to 70 wt.% of a C 1-4 alkyl methacrylate to total monomers having ethylenically unsaturated double bond and C. 0.1 to 10 wt.% of an organic hydroperoxide to total monomers having ethylenically unsaturated double bond.
