✦ 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 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
