ABSTRACT:
Disclosed are compositions and shaped articles comprising or produced from the compositions. The compositions can comprise (a) at least one polypropylene polymer and (b) at least one E/X/Y copolymer wherein E comprises ethylene; X is a monomer such as vinyl acetate and alkyl (meth)acrylic esters; and Y is one or more additional comonomers such as carbon monoxide; sulfur dioxide; acrylonitrile; maleic anhydride; maleic acid diesters; (meth)acrylic acid, maleic acid, maleic acid monoesters, itaconic acid, fumaric acid, fumaric acid monoester, and salts thereof; glycidyl acrylate, glycidyl methacrylate, and glycidyl vinyl ether in which, based on the E/X/Y copolymer, X is from 0 to 50 weight %, Y is from 0 to 35 weight % of said, X and Y cannot both be 0%, and E is the remainder.
