Abstract

The influence of die angle on the flow behaviour for high impact polystyrene (HIPS) melt is investigated by using a set of capillaries with a series of entry angles (2α) in this work. It appears that the melt flow basically obeys the index law; the dependence of apparent shear viscosity (η_a) on temperature roughly accords with the Arrhenius equation and the values of η_a changes with 2α to some extent. The end effect of the melt is significant under experimental conditions, and the end pressure losses (ΔP_ends) decrease with increasing 2α; there is a local minimal value of ΔP_ends at 2α around 75°. © 1997 Elsevier Science Ltd.
