Commercial samples of polypropylene were characterized in respect to their molecular weight and molecular weight distribution on the basis of quantitative information gained from their steady‐state flow behavior. The information obtained from this analysis was used to interpret the results of extrudate swelling, reinforcement of impact strength, and lowering of brittleness temperature. Manners of thermal and shear degradation were also studied.
