ABSTRACT:
A polymer blend comprising (a) a modified block copolymer comprising (i) a polystyrene block and (ii) a polydiene block or a hydrogenated polydiene block, said polydiene block or hydrogenated polydiene block being modified to contain an average of one or more carboxyl groups; and (b) a polymer comprising a polymerization reaction product of two or more mono-ethylenically unsaturated monomers in which (i) at least one of the monomers is an acrylic or methacrylic acid ester of a non-tertiary alcohol having 1 to 14 carbon atoms, inclusive and (ii) at least one of the monomers has carboxylic acid functionality and is present in an amount ranging from about 1 to about 15 parts by weight, based on 100 parts by weight of polymer (b), and a method of priming a substrate comprising applying the blend to the substrate.
