Abstract

The present invention relates to a polymer composition containing a copolymer, which copolymer contains monomer units of ethylene, an alpha-olefin and a non-conjugated diene, the polymer composition containing at least copolymer A and copolymer B, which copolymers contain monomer units of ethylene, alpha-olefin and a non-conjugated diene, the weight-average molecular weight of copolymer A being higher than that of copolymer B and at least copolymer A satisfying the relationship: Mw/Mn<-0.066.Deltadelta+a (1) where Mw is the weight-average molecular weight of the copolymer, Mn is the number-average molecular weight of the polymer, a=4.8 Deltadelta, expressed in degrees, is the difference between the loss angles at 0.1 rad/s and 100 rad/s, from the quotient of G''/G', where G' is the storage modulus is and G'' is the loss modulus, measured by means of mechanic, dynamic spectrometry. The invention also relates to a polymer composition where at least copolymer A is polymerized with a Ziegler-Natta catalyst containing a transition metal from group 3, 4, 5 or 6, an organometal from group 1, 2, 12 or 13 and a compound according to formula 1, with polymer A and copolymer B being mixed after polymerization.
