Abstract
Acrylic copolymer PSA compositions having enhanced peel strength without substantially decreasing sheer properties have been formulated by homogeneously incorporating the tackifying resin into the polymer matrix. The tackifying resin is dissolved into a solution of alkyl (meth) acrylate and (meth) acrylic acid monomers prior to polymerization.
