Abstract
There is provided a pressure-sensitive adhesive graft copolymer formed by reacting an acrylic monomer system comprising at least one alkyl acrylate ester containing from about 4 to about 8 carbon atoms in the alkyl group in the presence of a macromer selected from the group consisting of ethylene-butylene and ethylene-propylene macromers and mixtures thereof with each of said macromer having a molecular weight of from about 2,000 to about 30,000, a glass transition temperature of less than about 0.degree. C. and a terminal reactive group of acrylate or methacrylate.
