| description abstract | A bis-IndZrCl2 catalyst was synthesized and used for ethylene homo- and copolymerization. The activity of the catalyst increases with increasing Al/Zr ratio; optimum activity was reached at 60 8C. Mv of the polymer decreased as the polymerization temperature increased; increasing reaction pressure increased bothMv and catalyst activity. The copolymerization of ethylene with different a-olefins was studied using the same catalyst system. The results indicate that under identical conditions there was a general decrease in the rate of polymeri- zation as compared to the homopolymeriza- tion. The CCD and the lamellar thickness were investigated using DSC. The heterogeneity of the CCD increasedwith increasing comonomer content and molar mass. | en |
