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.
