The Measurement of the Elongational Viscosity of Polymer Solutions
A number of years ago the Chemical Engineering and Technology committee of the British Science Research Council decided that there was a lacK of commercial instrumentation for the measurement of elongational viscosity. Following an assessment of the field three instruments were selected for development. The long range intention was that these instruments should become commercially available. This paper describes one of these instruments and discusses the results which can be obtained from it. The instrument itself was constructed at the SRC’s Rutherford Laboratory as a result of joint discussions on design and the modification of the original.
