  • High Tg acrylic polymer and epoxy-containing blend therefor as pressure sensitive adhesive
    Patent number: 6686425
    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>20° C., optionally a C1-30 (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>50° C. When blended with at least one liquid epoxy resin, the resulting mixture exhibits desirable pressure sensitive adhesive properties and may be cured.
