Abstract
In this article, highly active and long-term stable Ziegler–Natta catalysts were formulated. 1-Octene and 1-decene homopolymerization and copolymerization were carried out with the prepared catalysts and the effect of catalyst formulation on the molecular weight and crystallinity level of polymers were investigated. Also, the valence state of Ti species was determined using X-ray photoelectron spectroscopy. The polymer molecular weights were determined by measuring the intrinsic viscosity. TC and degree of crystallinity were obtained from the second heating curve of differential scanning calorimetry analysis. Using these catalysts, polymerization conversion of long chain α-olefins was reached to higher than 95%.
