Abstract
The invention relates to a process for making e-Beam curable pressure sensitive adhesive compositions by derivatizing an acrylic polymer having one or more hydroxy groups or one or more acid groups with a derivatizing agent prepared from a hydroxy-functional acrylate monomer and a diisocyanate. The pressure sensitive adhesive can be effectively cured without a photoinitiator or reactive diluent. Also disclosed are e-Beam curable pressure sensitive adhesives made with the derivatizing agent and methods for adhering substrates with the pressure sensitive adhesive compositions.
