The reaction between the catalyst components in Ni (naph)2-TIBA.DBMP-BF3.OEt2 system which catalyzed the polymerization of butadiene have been studied by IR method. It was found that the main product in the reaction between TIBA and DBMP was iBu2AlOAr which could delay the reduction of Ni(II)
so as to stabilize the active center Ni(I). According to the analytical data of the products in the reaction between DBMP and TIBA
Ni (naph)2 and TIBA.DBMP and BF3.OEt2
an octahedra coordinated active center model was proposed.
