Impact of Polymerization Process Parameters on Improved Comonomer Incorporation Behavior in Ziegler?Natta Catalysis

Ziegler-Natta (ZN) based co-polymerization processes for the production of linear low-density polyethylene (LLDPE) generally give rise to a non-uniform incorporation distribution comonomer. It has been shown that lowering titanation temperature during catalyst synthesis can increase evenness this distribution. However, polymerization process parameters also affect resulting To investigate these factors, ZN system using variety comonomer-types, at various -concentrations and temperatures is studied. The molecular properties polymer samples obtained are analyzed by high-temperature size-exclusion chromatography (HT-SEC). more uniform comonomer be achieved either or concentration, both increases effect.
