ABSTRACT:
A polymer blend comprising (a) a block copolymer comprising (i) a polystyrene block and (ii) a polydiene block or a hydrogenated polydiene block, said block copolymer (a) being non-maleated; and (b) a polymer comprising a polymerization reaction product of two or more monoethylenically 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 is a nitrogen-containing monomer and, optionally, (iii) from 1-10 parts, based upon 100 parts of polymer, of a monomer having at least one of carboxylic acid functionality, hydroxy functionality, and epoxy functionality as well as a method of priming a substrate comprising applying the blend to the substrate.
