Abstract (en)

[origin: WO0198386A1] The invention concerns a syndiotactic polypropylene whereon is grafted a functional monomer. The invention also concerns a coextruding binder consisting (i) either of grafted syndiotactic polypropylene optionally diluted in at least a polyolefin (C1) or in at least a polymer having elastomeric character (D) or in a mixture of (C1) and (D), (ii) or of grafted isotactic polypropylene diluted in syndiotactic polypropylene and optionally in at least a polymer with elastomeric character (D). The invention also concerns a mutilayer structure consisting of a layer comprising said binder, and directly attached thereto a nitrogenous or oxygenated polar resin layer such as a polyamide resin layer (E), of a saponified ethylene and vinyl acetate copolymer (EVOH), a polyester resin, a mineral oxide deposited on a polymer such as PE, polyethylene terephthalate or EVOH, or even a metallic or metalloplastic coat. In another embodiment, the invention also concerns said structure and directly attached thereto, on the side on the binder, a polyolefin (F) layer.
