Abstract
A copolymer of ethylene and of a 1,3-diene of formula CH═CR—CH═CHis provided. The copolymer bears an amine function, the symbol R representing a hydrocarbon chain having from 3 to 20 carbon atoms. Such a copolymer improves the compromise between the content of ethylene in the polymer, its crystallinity and the stiffness of a rubber composition containing it.
