Abstract: Acrylic syrup polymer composition are provided by partially polymerizing a (meth)acrylic monomer mixture in the presence of a thiol chain transfer agent to produce a first syrup polymer composition comprising a low molecular weight solute (meth)acrylic copolymer and solvent monomers, quenching the chain transfer agent, further polymerizing the first syrup polymer composition to produce a second syrup polymer composition comprising the low molecular weight solute acrylic copolymer, a high molecular weight solute acrylic copolymer and optionally unreacted solvent monomers, optionally adding a crosslinker and photoinitiator; and further photopolymerizing the syrup polymer composition to produce a pressure-sensitive adhesive.

Abstract: A method for preparing an acrylate adhesive is provided by the steps of partially polymerizing a monomer mixture to provide a syrup polymer composition having a high molecular weight solute copolymer. This first syrup composition is again polymerized to provide a second syrup polymer composition having a low molecular weight copolymer. The second syrup polymer composition is provided with a crosslinking agent and further polymerized to provide the adhesive composition.
