<p>A polymer blend comprising (a) a block copolymer, in an amount sufficient to associate with the substrate, 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, in an amount sufficient to bond to block copolymer (a), comprising a polymerization reaction product of (i) at least one mono-ethylenically unsaturated acrylic or methacrylic acid ester of a non-tertiary alcohol having 1 to 14 carbon atoms, inclusive; (ii) at least one mono-ethylenically unsaturated nitrogen-containing monomer selected from the group consisting of an N-vinyllactam and N,N-dialkylacrylamide; and (iii) from 1-10 parts, based upon 100 parts of polymer (b), of a monomer having at least one of carboxylic acid functionality, hydroxy functionality, and epoxy functionality.</p> |
