Abstract:
1. A two-part adhesive composition comprising a component A adhesive portion and a component B activator portion, which portions are capable of being mixed in a 1:1 ratio to form elastic or ductile adhesives with improved properties, wherein component A comprises methyl methacrylate monomer and a free radical initiating species comprising a sulfur bearing compound selected from the group consisting of chlorosulfonated polymers, sulfonyl chloride and sulfimides, and a peroxide, wherein the peroxide is free of benzoyl peroxide, and component B comprises methyl methacrylate monomer and an amine promoter selected from the group consisting of tertiary aromatic amines and amine-aldehyde promoters, wherein either component A or component B or both further comprise a thermoplastic block copolymer component selected from the group consisting of wherein either component A or component B or both further comprise an adhesion promoting polymer, wherein component B does not include a chlorosulfonated polymer and wherein either component A or B or both further comprise a core shell impact modifier.
