Claims
- 1. A method of coating a substrate comprising the steps of:
- (1) applying to said substrate a crosslinkable composition comprising:
- (A) a polymer of ethylene and maleic anhydride containing
- (a) from about 42 to 99% by weight of structural units derived from ethylene;
- (b) from about 1 to 8% by weight of structural units derived from maleic anhydride; and
- (c) from 0 to about 50% by weight of structural 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; and
- (B) from about 1 to 10 parts by weight, based on 100 parts by weight of the polymer (A), of at least one polyepoxide compound; and
- (C) from about 0.02 to 2 parts by weight, based on 100 parts by weight of the polymer (A), of at least one catalyst suitable for reacting said anhydride functions with said epoxide functions to said substrate; and
- (2) reacting said crosslinkable composition at a temperature of from about 10.degree. to 160.degree. C., under a pressure of from about 1 to 300 bars and for at least about 0.5 hour.
- 2. The method of claim 1, wherein the substrate is an electric cable.
- 3. The method of claim 1, wherein in said crosslinkable composition the polymer (A) has a melt index of between 5 and 500 dg/min.
