Abstract
Styryl-modified acrylate polymer pressure sensitive adhesive beads, adhesive films made therefrom and methods of making the same. Surprisingly, the polymerization of styryl-functional monomer into bead formulations provides beads that can be easily extruded and made into adhesive films having high shear strength. The polymerization of styryl-functional monomer into bead formulations comprising methacrylic acid also obviates the need to use a modifier moiety.
