COMPOSITION BASED ON ISOTACTIC POLYPROPYLENE OBTAINED BY METALLOCENE CATALYSIS AND ON GRAFTED ISOTACTIC POLYPROPYLENE OBTAINED BY ZIEGLER-NATTA CATALYSIS

摘要

Composition comprising 50-99 wt.% of a metallocene isotactic polypropylene (co)polymer and 1-50 wt.% of a product (I) comprising 50-100 wt.% of a Ziegler-Natta isotactic polypropylene (co)polymer and 0-50 wt.% of a poly-1-butene, polystyrene and/or polyethylene (co)polymer, where (I) is grafted with a functional monomer. An Independent claim is also included for a multilayer structure comprising a layer of a composition as above attached to a polar nitrogen- or oxygen-containing layer, a layer of inorganic oxide deposited on a polymer, or a metallic or metalloplastic layer.
