An efficient method for the synthesis of ammonium octamolybdate with a quantitative yield has been developed.Compounds based on PVC plastic and octamolybdate are obtained. It was found that the introduction of ammonium octamolybdate in PVC plastic leads to an increase in the fire resistance of the compound and to a decrease in smoke formation during its combustion. At the same time, the mechanism for reducing smoke emission during PVC plastic combustion in the presence of ammonium octamolybdate consists in its catalytic action in the conversion of soot particles into various oxidized forms. It is shown that PVC plastics containing ammonium octamolybdate have elevated oxygen index and coke residue.
