| abstract |
The present invention relates to an elastomeric copolymer derived from components including a) ethylene, b) α-olefin, c) non-conjugated polyene (C) having one C = C bond that can be copolymerized using Ziegler-Natta catalyst, and d) optionally, non-conjugated polyene (D), which in the molecule contains two or more C = C bonds, which are capable of copolymerizing with the aid of a Ziegler-Natta catalyst. The copolymer differs, among other things, by the specific branching ratio of the sun. The present invention also relates to a method for producing such copolymers. |
