Claims20
A process for preparing a pre-adhesive copolymer composition comprising:
- a providing a syrup polymer composition comprising:
- 1) a first component solute acid functional (meth)acrylate copolymer,
- 2) a second component comprising at least one free-radically polymerizable solvent monomer comprising an acid functional monomer, and
- 3) a polyfunctional aziridine crosslinking agent;
- b) wherein the component of the syrup polymer composition are combined for a time, and a temperature sufficient to react, and
- c) adding additional acid functional monomers.
