ABSTRACT:
A crosslinking process wherein at a temperature of about 10.degree. to 160.degree. C., under a pressure of about 1 to 300 bars and for at least about 0.5 hour, a polymer, containing from about 42 to 99% by weight of units derived from ethylene and, where appropriate, also from an .alpha.-olefin, from about 1 to 8% by weight of units derived from maleic anhydride and from 0 to about 50% by weight of units derived from at least one additional monomer selected from an ester of an unsaturated carboxylic acid with an alcohol containing from 1 to 12 carbon atoms, is reacted with at least one polyepoxide compound, preferably present in an amount of from about 1 to 10 parts by weight, based on 100 parts by weight of the polymer, in the presence of at least one catalyst suitable for reacting the anhydride functions with the epoxide functions. The catalyst is preferably present in an amount from about 0.02 to 2 parts by weight, based on 100 parts by weight of the polymer. The crosslinkable compositions may be used to coat a substrate such as an electric cable.
