Abstract: A microporous membrane structure is disclosed that comprises a microporous membrane formed of a synthetic polymer and a substantially continuous porous coating on the membrane. The coating is formed from a urethane-based polymer, and provides a permeable barrier that does not interfere with the function of the membrane, and which will prevent further materials that are applied to or adjacent the membrane from interfering with the function of the membrane when those further materials are applied to the porous coating.

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.
