摘要：

A new type of shear gradient viscometer with automated recording of the time of fluid equilibration in a U-shaped capillary is introduced. Comparative measurements with a Zimm-Crothers-type viscometer were in good agreement. The Kuhn-Mark-Houwink relationships were established for extremely high molecular weight polystyrenes of up to Mw = 40 × 106 in toluene at 20 °C and in THF at 25 °C and were found to be linear over the entire observed range of molecular weights. © 1979, American Chemical Society.
