Adhesive composition

An adhesive composition comprising about 10-90 weight percent ester monomer, about 2-85 weight percent polymeric elastomer, about 0.02-10 weight percent initiator, about 0.1-5 weight percent phosphate ester, and about 1-80 weight percent vinyl-terminated liquid rubber, said ester monomer being selected from the group consisting of methacrylate ester monomers, acrylate ester monomers and mixtures thereof, said vinyl-terminated liquid rubber being selected from the group consisting of vinyl-terminated polybutadienes and copolymers thereof, vinyl-terminated polyisoprenes and copolymers thereof, and mixtures thereof.

An adhesive composition comprising about 10-90 weight percent ester monomer, about 2-85 weight percent polymeric elastomer, about 0.02-10 weight percent initiator, and about 1-80 weight percent vinyl-terminated liquid rubber, said ester monomer being selected from the group consisting of methacrylate ester monomers, acrylate ester monomers and mixtures thereof, said initiator being in a peroxide paste which contains at least 5 weight percent organic peroxide and less than 18 weight percent water.

A kit for providing a two-component reactive adhesive formulation, said kit comprising a Part A chamber and a Part B chamber, said Part A chamber containing a Part A composition, said Part B chamber containing a Part B composition which is reactable with said Part A composition, said Part A composition and said Part B composition being combinable in a preselected weight ratio to yield an adhesive composition comprising about 10-90 weight percent ester monomer, about 2-85 weight percent polymeric elastomer, about 0.02-10 weight percent initiator, and about 1-80 weight percent vinyl-terminated liquid rubber, said ester monomer being selected from the group consisting of methacrylate ester monomers, acrylate ester monomers and mixtures thereof, said vinyl-terminated liquid rubber being selected from the group consisting of vinyl-terminated polybutadienes and copolymers thereof, vinyl-terminated polyisoprenes and copolymers thereof, and mixtures thereof.
