Abstract: Disclosed pressure sensitive adhesive compositions, having enhanced heat resistance, obtained by the emulsion polymerization of (a) one or more acrylic acid ester or (meth)acrylate acid ester(s), (b) one or more hydroxyl functional (meth)acrylic monomer and (c) one or more ureido substituted (meth)acrylate monomers(s).

Abstract: A pressure sensitive adhesive composition is described. The pressure sensitive adhesive composition includes a polymerization product of a monomer mixture. The monomer mixture includes the following components: (a) at least one alkyl ester of (meth)acrylic acid or cyclic hydrocarbon acrylates; (b) at least one vinyl ester of a C4-C20 carboxylic acid; (c) at least one hydroxyl functional (meth)acrylate monomer, or at least one epoxy functional (meth)acrylate monomer; (d) at least one ureido substituted ethylenically unsaturated monomer; and one or more optional monomer components (e)-(g). The pressure sensitive adhesive composition provides a desirable combination of low and high temperature performance, and good adhesion to both metal and organic polymer surfaces.
