## 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

The catalytic activation process of the Ni-based Ziegler-Natta catalyst composed of Ni(naphthenate) 2 , catalytic amount of 1,3-butadiene, BF 3 β’OEt 2 and AlEt 3 , is spectroscopically observed by using synchrotron X-ray absorption and crystal field spectroscopies, and an optimum model of the nickel
