Acrylate hot melt adhesive containing zinc carboxylate.

摘要

An improved hot melt pressure sensitive adhesive composition comprises copolymerized monomeric acrylate or methacrylate ester of a non-tertiary alcohol, polar monomer such as acrylic acid, 2-polystyrylethyl methacrylate macromolecular monomer and sufficient zinc carboxylate to endow the composition with improved melt flow properties and cohesive strength. The invention also provides adhesive coated sheet materials comprising the adhesive composition coated onto a flexible sheet.
