<p>COMPOSITIONS FOR FORMING EPOXY ADHESIVE CONTAINING ACRYLATE RUBBER Reaction mixtures for forming curable epoxy resin compositions comprise a major amount of epoxy resin, a minor amount of monoethylenically unsaturated monomer capable of forming polyacrylate rubber, and a monomer soluble initiator. Optional ingredients include a crosslinking agent for the rubber-forming monomer, a grafting agent for rubber and epoxy resin, and an epoxy curing agent, preferably having activation conditions which are not satisfied when the initiator is activated. Heating the reaction mixture gives epoxy resin compositions containing polyacrylate rubber, the latter being optionally crosslinked and/or grafted to the epoxy resin. Activation of the curing agent, e.g., by heating, yields cured adhesive compositions.</p> |
