Abstract:
A high Tg acrylic polymer is provided as well as an epoxy-blend thereof for use as a pressure sensitive adhesive. The high Tg acrylic polymer comprises a copolymer of an alkyl (meth)acrylate monomer whose homopolymer has a Tg 20Â C. , optionally a C (meth)acrylate monomer, an nitrogen-containing polar monomer, and a polymerizable epoxy-containing monomer, with the monomers being present in an amount such that the copolymer has a Tg 50Â C. When blended with at least one liquid epoxy resin, the resulting mixture exhibits desirable pressure sensitive adhesive properties and may be cured.
