| abstract |
The invention relates to a rubber composition having adhesion to a natural rubber composition, said composition being at least based on 5 to 95 phr of polyisoprene having a percentage by weight of 1,4-cis bonds of at least 90% of the weight of the polyisoprene; 5 to 95 phr of ethylene copolymer and of a 1,3-diene of formula CH2=CR-CH=CH2, wherein the ethylene units in the copolymer represent more than 50 mol% of the monomer units of the copolymer, the symbol R representing a hydrocarbon chain having 3 to 20 carbon atoms; and a crosslinking system. The invention also relates to a pneumatic tire, in particular a pneumatic tire provided with a sidewall comprising said composition. |
