Abstract
Abstract A polymeric composition of matter comprises a polymer having dispersed therein at least one of colloidal metal and metal oxide particles in the submicrometer size range, said composition being aqueous-free and free of aliphatic hydrocarbon polymers and their halogenated derivatives. Methods for preparing the dispersions of the invention are also disclosed.
