A Weissenberg hheogoniometer was m ~d i f i e d l -~ to improve sample temperature uniformity and constancy (to within f0.5'C) and to give a quicker response to normal thrust changes (estimated gap change 50.1 fim/kg thrust; gap angle = 8.046'; gap radius = 1.2 cm; servomechanism replaced by an open
Measurements were taken of the viscoelastic properties of six polymer melts by mean of the Weissenberg rheogoniometer and the Han slit/capillary rheometer. Polymers in vestigated were three high-density polyethylenes of different polydispersity, a low-den sity polyethylene, a polypropylene, and a po
