The generations of Ziegler-Natta catalysts for polymerization of α-olefins

In this study, the recent advances in the area of olefin polymerization have been reviewed and the study is allocated to the six generations of Ziegler-Natta catalysts, which have been improved during five recent decades up to now. The focus is on the fifth generation area in which we have started a study for preparing of a new catalyst with diether donors. Beside this, some recent papers about preparing of diether catalysts have been reviewed and the space molecular structure of the diether is presented.
