On the characterization of non‐newtonian flow

摘要

AbstractA rheological distribution factor has been derived from well‐known relations. It is compared with experimental data with the use of conventional ratios of molecular weights such asMw/Mn. Data on polyisobutylene, polystyrene, and high density polyethylene are presented. An equation of flow has also been derived from experimental data. It has been used to describe the non‐Newtonian flow of various polym
