HIGHLY TACKIFIED, HOT MELT PROCESSABLE, ACRYLATE PRESSURE SENSITIVE ADHESIVES

摘要

The methods of preparing hot melt processable pressure sensitive adhesives include combining an elastomeric (meth)acrylate random copolymer contained within a thermoplastic pouch and greater than 50 parts by weight per 100 parts by weight of hot melt processable elastomeric (meth)acrylate random co-polymer of at least one tackifying resin in a hot melt mixing apparatus, and mixing to form a hot melt processable pressure sensitive adhesive. 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.
