Abstract
A process for rendering polymer compositions antistatic and the products of such process are described. The polymeric material is treated with a combination of selected trineoalkoxy amino zirconates and trineoalkoxy sulfonyl zirconates. These latter materials are soluble in the polyolefins, polyesters, polyamides, polyethers, polycarbonates, and polystyrenes and remain stable during the processing of these polymers. Furthermore, the antistatic agents of the invention are thermally stable to temperatures up to 825.degree. F., do not 'bloom' during the polymer processing, and are colorless, permanent, non-blooming and non-moisture dependent.
