Abstract
A process includes first preparing an adhesive composition containing electron beam-curable PSA polymer matrix, fillers and solvent. The composition is introduced and conveyed through a twin screw extruder. In the extruder, solvent is removed in one or more solvent removal units, and a solvent-free composition is extruded as the carrier layer. Skin layers may be co-extruded with the carrier layer.
