ABSTRACT:
A polymeric flame retardant composition comprises low melting temperature phosphate-sulfate glass compositions in an amount of from about 10 to about 100 parts by weight per 100 parts by weight of said polymer. Desirably, the polymer is a halogen-containing polymer. The phosphate-sulfate combination has been found to produce synergistic results.
