“…The double charged Ba 2þ cations on the surface of the BaSO 4 crystals are centers for the adsorption of such electron donors as carboxylic or carbonyl groups. The contribution of the anions to the adsorption of polar molecules has been found to be low [9,10].…”

Polypropylene (PP) composites were prepared by compounding PP with untreated, as well as treated barium sulphate. Barium sulphate filler had been treated with different surface modifiers such as sodium dodecyl benzene sulphonate (SDBS), polyoxyethylene sorbitan monooleate (Tween 60) and oleic acid. The mechanical properties of the prepared composites were evaluated. It was found that the filler treatment with SDBS enhanced the tensile yield strength and hardness of the resulting composites and also the elongation at rupture for most of the composites. Tween 60 and oleic acid as treating agents for the filler had the same effect on the tensile yield strength, while increasing their amounts on the surface decreased the elongation properties of the composites.
