WebEven small amounts of a high molecular weight polymer can affect the processing behavior and so does the melt rheology. Molecular weight distribution (MWD), molecular weight (MW) and branching are the important parameter used for defining rheology of the polymer melts. While the increase in molecular weight improves the viscosity, any changes ...
