Long chain branching in ethylene polymerization using constrained geometry metallocene catalyst
Abstract
We report an experimental investigation on long chain branching (LCB) in ethylene polymerization with the Dow Chemical's constrained geometry catalyst system, CGC‐Ti/TPFPB/MMAO, using a continuous stirred‐tank reactor (CSTR) at 140°C, 3.45 × 103 kPa, and a mean residence time (τ) of 4 min. The effects of the catalyst (CGC‐Ti) and co‐catalyst (TPFPB and MMAO) concentrations on the catalyst activity, polymer molecular weight, and shear thinning …
