ABSTRACT:
Several organic acid reactive comminuted minerals, which are generally used as fillers for plastics, rubber, etc., are treated with unsaturated organic acids, alone or in admixture with saturated acids, antioxidants and, alternatively, liquid agents. The surfied (surface modified) fillers thus obtained have excellent wetting and dispersion in both polar and non-polar media as exemplified by their superior packing fractions. Unsaturated acids, alone or in admixture with saturated acids, do not yield fillers stable to the effects of oxidation, both in preparation and use. It has been discovered that very low concentrations of antioxidants stabilize the surfied filler against oxidation and resulting instability. Liquid agents also have been discovered to add a new dimension to the art by cooperating with the acid surfiers (surface modifiers) to modify the interface between the filler and matrix to a greater extent than by previously available techniques. These surfied fillers are thus valuable adjuncts in formulating plastics and related compositions.
