Abstract

C. L. Rohn made a detailed analysis of the blown film process and showed how poly(butene-1) film properties can be predicted. His analysis is based on the theory of A. V. Tobolsky and L. L. Cnapoy, which predicts that the Maxwell-Wiechert model adequately describes the steady-state elongational flow of polymer melts, as well as melt fracture. Furthermore, this theory predicts that extensional flow can be adequately described by simple shear viscosity measurements. This theory has been tested in this paper.
