Abstract

Flame resistant moulded halogen-containing polymer articles which contain antimony oxide are advantageously obtained by adding a soluble antimony compound which gives rise to an antimony oxide to the solution of halogen-containing polymer in an organic solvent, producing the moulded polymer article from the polymer solution and converting the antimony compound to antimony oxide in this article before or during the after-treatment.
