What are the best characteristics chosen of Ostwald viscometer (capillary diameter, viscosity range) to measure viscosity of transformed rigid PVC?

05 December 2020 0 9K Report

Hello everyone, for the purpose of determining the kinematic viscosity of PVC transformed into a rigid tube dissolved in a dilute solution of cyclohexanone or THF. What are the best characteristics chosen of Ostwald viscometer (capillary diameter, viscosity range) to measure the kinematic viscosity of transformed rigid PVC? Thanks in advance
