EXPERIMENTAL STUDY OF THE STRAIN OF A POLYMER JET
O. I. Skul'skii, E. V. Slavnov, A. I. Sudakov, and N. V. Shakirov UDC 532.522:532.135 Results of experimental investigation of the postspinneret extension of a plasticized-polyvinylchloride melt have been presented. The influence of the stretching rate and the length of the strain zone of the jet profile has been investigated. A formula describing the time change in the axial velocity has been proposed.
