Abstract
Clays and organoclays which are treated with resorcinol diphosphate and/or bisphenol diphosphate as general nanoparticle particle dispersants and replacements for quaternary amines. The two compounds are used as self activating and self dispersing nanoparticles by localizing themselves on the particle surface in a polymer matrix and acting as a nanoparticle dispersants in general, as well as resulting in exfoliation of clays. The exfoliate clays may be used in polymers in lieu of other organic treatments.
