In this study of polymer rheological properties, we make use of a generalized Mx
method of calculating polymer molecular weight (MW) averages from a GPC experiment [1]. The MW polydispersity result based on this new GPC-Mx approach is shown to be more suitable to account for the effect of different parts of polymer molecular weight distribution (MWD) on rheology measurements at different shear
rates, than do the traditional polydispersity indices based on the ratio of Mz, Mw and
Mn values. |
