ABSTRACT:
Polymer systems can be rendered flame retardant by adding a source of halogen and particles of antimony pentoxide that have been dried from colloidal dispersions that have been treated with certain metal ions. The properties of the polymer are conserved when the colloidal dispersion is treated with ions of metals that have insoluble antimonates before drying to form a powder.
