Abstract Capillary rheometry is used to study the effect of fillers (carbon black, calcium carbonate, talc, and titanium dioxide) on the apparent viscosity of plasticized poly(vinyl chloride). It was found that viscosity shows a minimum at about 5 percent filler volume content, for CaCO 3 , Talc, and TiO 2 . An assumption is presented relating this phenomenon with the ability of filler for plasticizer absorption, i.e., with filler surface area.
