Abstract
Crosslinkable compositions with a polyethylene base are described which comprise a major proportion, for example 65 to 95% by weight, of at least one polymer selected from the polyethylenes grafted by a silane and ethylene-triethoxyvinylsilane copolymers; a minor proportion, for example, from 5 to 35% by weight, of at least one polymer selected from the hydrophilic polymers which are incompatible with ethylene polymers; as well as, added to the total weight of polymers (a) and (b), a small proportion, for example, from 1 to 10% by weight, of at least one polymer selected from the copolymers and the terpolymers with an ethylene base to react chemically with said incompatible hydrophilic polymer; and a catalytic proportion, for example of 0.001 to 0.3% by weight, of at least one hydrolytic catalyst. These crosslinkable compositions can be shaped by extrusion, extrusion blow-molding or injection molding and then crosslinked by heating in the presence of water.
