Beschreibung
Zusammenfassung:	Coextruded multilayer complexes by the use of polyolefins and of impact-modified impermeable resin compositions based on hydrolysed vinyl acetate/ethylene copolymers comprising, by way of additive for improving the impact resistance, ethylene/propylene elastomer copolymers modified by grafting alpha , beta -ethylenically unsaturated carboxylic acid and, preferably, by maleic anhydride. The coextruded multilayer complexes are especially suitable for producing fuel tanks combining impact resistance and high impermeability to petrol and to petrol-alcohol mixtures.
