Abstract:
A high Tg acrylic polymer comprised of the polymerization reaction product of the following monomers:(1) an alkyl (meth)acrylate monomer whose homopolymer has a Tg>20Â° C. present in an amount ranging from 20 to 80 percent by weight; (2) optionally a C1-30 (meth)acrylate monomer present in an amount of up to 50 percent by weight; (3) a nitrogen-containing polar monomer present in an amount ranging from 5 to 20 percent by weight; and (4) a polymerizable epoxy-containing monomer present in an amount ranging from 30 to 50 percent by weight, said monomers being present in an amount such that the Tg of said copolymer is greater than 50Â° C.
