Original Abstract Submitted
A composition of matter is provided for preparing a foamed polymer adhesive includes a reactive mixture, a free radical-producing catalyst, and a foaming agent. The reactive mixture includes methacrylate ester monomer and a thermoplastic polymer soluble therein. The polymerization reaction causing shrinkage of the reactive mixture. The foaming agent causes expansion of the reactive mixture to form a closed celled foam that offsets at least in part the shrinkage of the reactive mixture caused by the polymerization reaction. The foaming agent includes an acid-neutralizing base and a second part being an acid that is ethylenically saturated or aromatic. A substrate is bonded by the adhesive independent of an intervening primer. The adhesive can be formed at a variety of densities and prevents print through on opposing sides of the substrate. A substrate with an oxide or oil coating can be bonded without removal of the coating.
