Abstract
Multilayer composites coextruded with the use of polyolefins and of impact-reinforced impervious resin compositions based on hydrolysed copolymers of vinyl acetate and ethylene comprising, as an additive improving the impact strength, elastomeric copolymers of ethylene and propylene which are modified by grafting an .alpha.,.beta.-ethylenically unsaturated carboxylic acid and, preferably, by maleic anhydride. The coextruded multilayer composites are very particularly suitable for the manufacture of fuel storage vessels combining impact strength and high imperviousness to petrol and to petrol/alcohol mixtures.
