The invention relates to a copolymer of ethylene and of a 1,3-diene of formula (I) which comprises ethylene units and 1,3-diene units, the ethylene units representing between 50 mol% and 95 mol% of the ethylene units and of the 1,3-diene units, and the 1,3-diene units of 1,4 configuration representing more than 50 mol% of the 1,3-diene units of formula CH2=CR-CH=CH2, the symbol R representing a hydrocarbon-based chain containing 3 to 20 carbon atoms. Such a copolymer exhibits an improved compromise between ethylene content, rigidity and degree of crystallinity for use in a tyre.
