SOUND DAMPING ADHESIVE

摘要

Acrylic based adhesives and constructions are described and claimed. The adhesives comprise on a copolymerized basis, (A) from about 50 to about 90% by weight of at least one alkyl acrylate, alkyl methacrylate, and mixtures thereof, wherein the alkyl group contains at least four carbon atoms, (B) from about 10% to about 30% by weight of at least one ethylenically unsaturated carboxylic acid or anhydride monomer, and (C) from about 0 to about 40% by weight of a monoethylenically unsaturated comonomer. The acrylic based adhesives of the invention exhibit desirable sound/vibration damping properties.
