Abstract

Disclosed are ethylene and butadiene copolymers and a catalytic system usable for the synthesis of these copolymers. The copolymers have a molar content of units resulting from butadiene of ≧8%, said units comprising trans-1,2 cyclohexane linkages, and a number-average molecular mass Mn of ≧40,000 g/mol. The catalytic system includes:
