Abstract: A process for rendering polymer compositions antistatic and the products of such process are described. The polymeric material is treated with selected amino and sulfonyl titanates and zirconates.

Abstract: Liquid mixtures of trialkylphosphine oxides, useful as antistats in thermoplastic polymers, are obtained by alkylating excess phosphine with a mixture of higher .alpha.-olefins to give a mixture of higher alkylated phosphines and unreacted phosphine and alkylating that mixture with a lower .alpha.-olefin. This method provides a larger percentage of higher alkyl groups and a lower percentage of lower alkyl groups compared to alkylating the phosphine with all of the mixed .alpha.-olefins in a single reaction. The shift in higher alkyl groups decreases the volatility of the trialkylphosphine mixture and is an advantage when preparing plastic compositions at higher formulation temperatures.

Abstract: Polyethylene having a relatively high specific gravity is modified to inhibit the production of static charges. A weak salt having properties of ionizing and having its positive ions bond chemically to the polyethylene is mixed in the polyethylene. A chemical agent is also dispersed in the polyethylene and is provided with properties of facilitating the dispersion of the positive ions of the weak salt throughout the polyethylene of high specific gravity for chemical bonding to the polyethylene. The weak salt may be cupric acetate and the chemical agent may be an amine. The amine is preferably ethoxylated. The material of this invention may be formed as non-transparent bags or as sheets. The material may be formed by mixing the different chemicals and extruding the mixture under conditions of controlled temperatures and pressures and for controlled dwell times.
