Abstract
Antistatic compositions are disclosed comprising a binder and a nonionic surface-active polymer having polymerized alkylene oxide monomers and an alkali metal salt characterized in that the composition is heterogeneous, comprises on a dry basis, at least 7 weight percent polymerized alkylene oxide monomers and the binder is selected from the group consisting of a particulate material and a mixture of particulate materials with hydrophilic materials.
