Extensional flow of polystyrene melt

  • R. L. Ballman
Article

Summary

The extensional flow of molten polystyrene was studied in the strain rate range of 7.8×10−4 sec−1 to 2.2×10−2 sec−1 at a test temperature of 300‡F (149 ‡C) Extensional viscosity was compared to shear viscosity measured at the same degree of stress and temperature and found to be from 3 to 350 times greater in magnitude but much less stress dependent.
