摘要:

A novel precision capillary viscometer which has a time resolution of ±0.001 s is reported. The viscometer has been utilized to demonstrate that estimates of intrinsic viscosity (to within 3% of the infinite dilution value for polystyrene in benzene) can now be made, over a wide range of polymer molecular weights, for solutions from a single polymer concentration.
