Abstract
The methods of preparing hot melt processable pressure sensitive adhesives include combining an elastomeric (meth)acrylate random copolymer and a discontinuous fibrous material in a hot melt mixing apparatus, and mixing to form a hot melt processable pressure sensitive adhesive. The elastomeric (meth)acrylate random copolymer may be contained within a thermoplastic pouch, and the hot melt mixture may include a relatively high level of tackifying resin. The elastomeric (meth)acrylate random copolymer may contain branching agents and photosensitive crosslinking agents. The hot melt processable pressure sensitive adhesives can be used to prepare transfer tapes.
