Patent ID: 7964249

Claim:
A process for preparing a polyacrylate pressure-sensitive adhesive, said process comprising the following steps: a) forming a saturated polyacrylate polymer by polymerization; b) combining the saturated polyacrylate polymer formed in a) with a polyfunctional α-cleaving α-hydroxy ketone initiator present in oligomeric form to form a polymer/initiator combination; c) processing the polymer/initiator combination formed in b) by a hot-melt process to form a hot-melt processed polymer/initiator combination; d) adding at least one amine acrylate to the hot-melt processed polymer/initiator combination formed in c); and e) crosslinking the saturated polyacrylate polymer by exposing the hot-melt processed polymer/initiator combination formed in d) to ultraviolet radiation.
