摘要： A copolymer comprising repeating units derived from ethylene, at least one C3-C20-α-olefin, at least one non-conjugated diene, and at least one dual polymerizable diene, wherein the copolymer has



(i) an intensity ratio D of ≤0.5 and
(ii) a molecular weight distribution (MWD)≥R, wherein R depends on the branching index g′(III) of the copolymer and
wherein R is −27.7 times g′(III)+29.2, when g′(III) is ≤0.90; and R is 4.3 when g′(III) is >0.90 and up to 0.99.




Also provided is a catalyst composition for making such copolymers containing at least two different metal complexes, a process for making the catalyst composition, a process for making the copolymer and to articles obtained with the copolymer.
