Abstract

A unique development in metallocene catalysis is the preparation of polyethylene with a long chain branching molecular structure by using a catalyst with constrained ligand geometry. The long chain branching polyethylene (LCBPE) existing in the PE product shows many unique rheological properties such as higher shear rates. A new method that can be used to prepare long chain branched PP with a relatively well-defined molecular structure was reported. The long chain branching structure is strongly supported by the formation of imide linkages and the reduction of overall hydrodynamic volume.
