摘要： The present disclosure relates to a novel metallocene compound. The metallocene compound according to the present disclosure may be used for the preparation of an olefin-based polymer, may have excellent ability, and may produce an olefin-based polymer having a relatively high molecular weight compared with the case of using a catalyst composition having a similar structure due to the structural and electrical steric hindrance effect.

摘要： Disclosed herein are ethylene-based polymers generally characterized by a density from 0.89 to 0.93 g/cm3, a ratio of Mw/Mn from 3 to 6.5, a Mz from 200,000 to 650,000 g/mol, a CY-a parameter at 190° C. from 0.2 to 0.4, and a reverse short chain branching distribution. The ATREF profile of these polymers can have a high temperature peak from 92 to 102° C., and a low temperature peak from 18 to 36° C. less than that of the high temperature peak. These polymers can have comparable physical properties to that of a metallocene-catalyzed LLDPE, but with improved processability, shear thinning, and melt strength, and can be used in blown film and other end-use applications.
