ELASTOMERIC COPOLYMER

摘要

The invention relates to an elastomeric copolymer comprising 25-85 wt.% of ethylene, 15-75 wt.% of alpha -olefine and optionally up to 20 wt.% of diene. It is characterized in that the copolymer has a Uniform Branching Coefficient, UBC, which satisfies the relation (a). The invention also relates to a process for the preparation of such an elastomeric copolymer. In this process a catalyst having a reactivity factor RF < 10 is used.
