The present invention relates to a composition comprising isotactic polypropylene homo- or copolymer obtained by metallocene catalysis (A), abbreviated to miPP, and isotactic polypropylene homo- or copolymer obtained by Ziegler-Natta catalysis (B), abbreviated to zniPP, and grafted. It also relates to a coextrusion tie comprising such a composition. It also relates to a multilayer structure comprising a layer (L) comprising the preceding tie and, directly attached to this layer: a nitrogen-comprising or oxygen-comprising polar layer (J), such as a layer of polyamide resin, of saponified ethylene/vinyl acetate copolymer (EVOH) or of polyester; a layer (J) of an inorganic oxide deposited on a polymer, such as polyethylene (PE), poly(ethylene terephthalate) (PET) or EVOH; or a metal or metalloplastic layer (J).
