Abstract: A composition comprising a blend of a first curable ethylene-copolymer and a second curable ethylene-copolymer wherein



(i) the first curable ethylene copolymer comprises from 50 % to 75 % by weight, based on the total weight of the first copolymer, of units derived from ethylene, from more than 0.5% and up to 5.0% by weight, based on the total weight of the first ethylene copolymer, of units derived from one or more diene selected from the group consisting of non-conjugated dienes having from 10 to 30 carbon atoms and comprising at least two cyclic units and having at least two endo-cyclic double bonds, and further comprising at least 15% by weight, based on the total weight of the first ethylene copolymer, of units derived from propylene, and wherein the total weight of the first ethylene copolymer corresponds to 100%;
(ii) the second curable ethylene copolymer comprises from 45% to 65% by weight, based on the total weight of the second copolymer, of units derived from ethylene, from about 0.5% to 12% by weight of units derived from one or more diene selected from the group consisting of non-conjugated dienes having from 8 to 24 carbon atoms and having at least one cyclic unit and having an endocyclic double bond and a no-terminal exocyclic double bond, and further comprising at 25% by weight, based on the total weight of the second ethylene copolymer, of units derived from propylene, and wherein the total weight of the second ethylene copolymer corresponds to 100%;
(iii) wherein the weight ratio of the first to the second ethylene copolymer is from about 1:10 to 10:1. Also provided are methods of making the compositions and applications of the compositions.
