Surface properties of a calcium carbonate filler treated with stearic .

The fixation of stearic acid on a CaCO3 filler and the induced changes in surface properties have been studied. The chemisorption isotherm of stearic acid was established using a tracer (tritium) method. Nitrogen adsorption, contact angle measurements and inverse gas chromatography at infinite dilution revealed a drastic.
