The study of flows of concentrated polymer systems in the channels of spinnerettes is important from the viewpoint of intensifying the formation of chemical fibers. It is also of considerable interest to investigate the expansion of jets of polymer liquids at the outlet of such channels and to predict the degree of expansion. In this study measurements were made of the distribution of longitudinal stresses in the flow of polymer systems in plane channels. The coefficients of expansion of free jets leaving cylindrical channels are also measured. The experimental data is compared with calculated results with good agreement.
