The effects of phosphine ligands on the polymerization of 1,3-butadiene with Co(2-ethyl hexanoate) 2 /AlEt 2 Cl/H 2 O were investigated. Although the polarizability of phosphine ligands, i.e. the ratio of the average dipole moment to the molecular volume, had moderate impact on 1,4-cis stereoregular

## Abstract Activation process and active site of Coβbased ZieglerβNatta catalysts were studied by using synchrotron Xβray absorption spectroscopic technique and an optimum model of the cobalt active site was proposed with density functional theory (DFT) calculations. In the Xβray absorption near e
