Abstract
Polymeric compositions comprise fine particles of an ammonium salt and a metal oxide, hydroxide, or salt, the metal salt having a weaker anion than the anion of the ammonium salt, dispersed in a polymeric film-forming binder. Specified binders are polyvinyl butyral, polyvinyl carbazole, polyvinyl chloride, polyvinylidene chloride, styrene-butadiene copolymers and cyclized rubber. The ammonium salt may be the sulphate, nitrate, chloride, phosphate or the benzene- or toluene-sulphonate and the preferred metal compounds are those of calcium, magnesium or lead.
