Numerical Modeling of p-v-T Rheological Equation Coefficients for Polypropylene with Variable Chalk Content

The paper reports the experimental results of a study investigating the effect of different contents of a mineral filler on the rheological properties, p-v-T, of polypropylene. Using the pvT100 apparatus, we measured specific volume under isobaric cooling at different pressures for pure polypropylen...
