ABSTRACT:
The invention relates to copolymers of alkenes and conjugated dienes containing cyclopropane and cyclopentane rings in the main chain. These copolymers are charachterised in that the amount of cyclopropane units is between 0.1% and 50% by weight and that the molar percent of the cyclopropane units is higher than the molar percent of the unsubstituted cyclopentane units.
