The hydrophobic and hydrophilic components of the surface of talc materials in aqueous solution were determined using ionic surfactants and their polar headgroup adsorption isotherms. The hydrophilic and hydrophobic surface areas are inferred from the amount of probe molecule adsorbed and the struct

✦ Synopsis
Talc has become an important filler for polyolefins but the optimum properties of filled polymer compositions are only achieved when using surface modified talcs. The possibility of chlorinating talc, using CCl 4 at 600 °, is demonstrated.

Talc-filled polypropylene (PP) composites were prepared by extrusion in a wide composition range (0-40 wt %). T o improve the affinity relation between talc and the PP matrix, we modified the talc surface with silane coupling agents. Differential scanning calorimetry investigations on test samples,
Talc samples in both sheet and powder form are studied by adsorption calorimetry and adsorption isotherm techniques. A model is used to determine the solid surface energy, the solid surface tension and the dispersive, acidic, and basic components of these terms. These results are introduced in an ap
