Abstract:
A blend of ethylene vinyl acetate copolymer (EVA) and a substantially random interpolymer comprising, based on the weight of the blend, between about:(A) 15 and about 85 weight percent EVA, and(B) 85 and about 15 weight percent of the substantially random interpolymer, wherein the substantially random interpolymer has a number average molecular weight (Mn) of at least 5,000.wherein the substantially random interpolymer comprises:(a) from about 1 to about 65 mole percent of polymer units derived from (i) at least one vinyl aromatic monomer, or (ii) at least one aliphatic or cycloaliphatic vinyl or vinylidene monomer, or (iii) a combination of at least one vinyl aromatic monomer and at least one aliphatic or cycloaliphatic vinyl or vinylidene monomer, and(b) from about 35 to about 99 mole percent polymer units derived from at least one C.sub.2 -C.sub.20 .alpha.-olefin, and, optionally(c) polymer units derived from one or more ethylenically unsaturated polymerizable monomers other than those of (a) and (b).
