Popis:	It has been established that the concentration of 1,4- cis -links and the molecular mass of polybutadiene obtained with cis -regulating systems containing nickel change in a parallel fashion. The hypothesis is expressed and experimentally confirmed that the decisive role in regulating both the molecular mass and also the structure of the polybutadiene is taken by an intermediate σ-organometallic derivative in which there is a β c-h bond existing in a σ, π-hyperconjugation interaction with the transition metal.
