ABSTRACT:
A process for making an adhesive comprising allowing a carrier web coated with a thermal free-radically polymerizable mixture to remain in a heat exchange medium for a time sufficient to subdue the reaction exotherm and maintain a reaction temperature by thermal contact of the polymerizable mixture with the heat exchange medium and to affect conversion of the coating to an adhesive layer, preferably to a pressure sensitive adhesive layer, wherein the coating is a substantially solvent-free thermally initiated polymerizable mixture comprised of at least one free radical monomer, at least one thermal initiator, optionally, at least one cross-linker and optionally, at least one co-monomer.
