Abstract
An antistatic composition comprising an admixture of a water soluble polymer of a quaternary ammonium salt and a an amino or sulfonyl titanate or zirconate composition. The titanate or zirconate composition is present in the admixture in an amount sufficient to reduce the moisture sensitivity of the quaternary ammonium salt polymer while retaining its antistatic properties. The antistatic properties of the composition are greater than the additive antistatic properties of the polymer and the titanate or zirconate composition. An associated method and coated antistatic surface are also disclosed.

An antistatic composition comprising:
- an admixture of,
- a water soluble polymer of a quaternary ammonium salt;
- and
- a water soluble metal oxide composition selected from the group consisting of amino titanates, sulfonyl titanates, amino zirconates and sulfonyl zirconates;
- wherein said water soluble metal oxide composition is present in said admixture in an amount sufficient to reduce the moisture sensitivity of said quaternary ammonium salt polymer while retaining its antistatic properties and to give the admixture antistatic properties that are greater than the additive antistatic properties of said quaternary ammonium salt polymer and said metal oxide composition.
A composition for being applied to surfaces to provide those surfaces with antistatic properties, said antistatic composition comprising:
- an aqueous solution of
- a water soluble polymer of a quaternary ammonium salt;
- and
- a water soluble metal oxide composition selected from the group consisting of amino titanates, sulfonyl titanates, amino zirconates and sulfonyl zirconates;
- wherein said water soluble metal oxide composition is present in said solution in an amount sufficient, when said solution is deposited on a substrate and water substantially removed, to reduce the moisture sensitivity of said quaternary ammonium salt polymer while retaining its antistatic properties and to give the substrate surface antistatic properties that are greater than the additive antistatic properties of said quaternary ammonium salt polymer and said metal oxide composition.
A surface with antistatic properties comprising:
- a substrate;
- and
- an antistatic composition on said substrate, said antistatic composition comprising:
- an admixture of a water soluble polymer of a quaternary ammonium salt and a water soluble metal oxide composition selected from the group consisting of amino titanates, sulfonyl titanates, amino zirconates and sulfonyl zirconates,
- wherein said water soluble metal oxide composition is present in said admixture in an amount sufficient to reduce the moisture sensitivity of said quaternary ammonium salt polymer while retaining its antistatic properties and to give the admixture antistatic properties that are greater than the additive antistatic properties of said quaternary ammonium salt polymer and said metal oxide composition.
