<p>Novel composition (I), grafted with a functional monomer, comprises (wt.%): an isotactic polypropylene homo- or copolymer produced with a metallocene catalyst (10-100); a polyethylene homo- or copolymer (0-90); and an isotactic polypropylene homo- or copolymer produced with a Ziegler-Natta catalyst and/or a poly-1-butene homo- or copolymer and/or a polystyrene homo- or copolymer (0-90). An Independent claim is also included for a multilayer structure comprising a layer of (I) and either: (a) a layer of polar, nitrogen- or oxygen-containing material; (b) a layer of a polymer coated with an inorganic oxide; or (c) a metallic or metalloplastic layer.</p> |
