摘要： The invention relates to an elastomeric copolymer derived from components comprising a) ethylene, b) an alpha-olefin, c) a non-conjugated polyene (C) having one C=C bond that is copolymerizable using a Ziegler-Natta catalyst, and d) optionally a non-conjugated polyene (D) which in the molecule contains two or more C=C bonds that are copolymerizable using a Ziegler-Natta catalyst. The copolymer is characterized by, inter alia, a specific branching coefficient BC. The invention also relates to a process for the preparation of such copolymers.
