Abstract

Preparation of new, useful and novel highly electro-conductive polymer compositions via the dispersion of electrically conductive particulates in conjunction with small proportions of certain organo aluminates, titanates and/or zirconates in polymeric substrates is hereinafter described. Further the production of heretofore unknown classes of organo aluminates, titanates and zirconates useful in the practice of this invention is disclosed and generically useful subclasses of these compounds defined. Advantages other than improved electrical conductivity of the resultant composites, i.e., process and physical property improvements are also documented for compositions containing said additives and particulate materials and/or composites in polymeric dispersions, and/or compositions of said particulates with said organic aluminates, titanates and zirconates.
