    Abstract: Polyacetals comprising oxymethylene and oxyalkylene units in the main chain of the macromolecules are stabilized against the action of heat and oxygen by means of secondary alkali metal phosphates. Thermoplastic molding compositions prepared from the stabilized polyacetals are suitable for the manufacture of finished and semi-finished products, for example molded articles, household utensils, and parts of machines.
