| Abstract: | The ESR spectrum of the retrofit nickel catalyst system showed that the active center consists of Ni(I) in the system and that the premix of Bd with nickel naphthenate before adding Al(i-Bu)2OC8H17 and BF3OEt2 to the system leads to stabilization of the Ni(I) complexes and the induced period of polymerization of butadiene shorter. The overall energy of polymerization of butadiene do not change. |
