The Effect of Pressure on Melt Viscosity of High Impact Polystyrene Containing Antimony Trioxide

  • F. Večerka

Abstract

A considerable attention has been devoted to the organic polymers modified by solid additives dispersed in polymer matrix. The additives used to improve some properties of polymer (or just only as a filler) affect, besides the properties in solid phase, the rheological behaviour of polymer melts. The influence of solid particles suspended in molten polymers on flow behaviour were studied by many authors. Most of fundamental information on the multiphase (polymeric) systems is summarized in the monography of Han /1/. However, while the effect of temperature and shear rate on rheological properties of such systems were intensively studied, the effect of pressure has not been considered for the time being.
