A flame retardant composition for resinous compositions, especially for mixtures of polyphenylene ethers and styrene resins, comprises a mixture of triaryl phosphates including at least one such phosphate wherein 1 or 2 of its 3 aryl groups are mesityl groups and its remaining group or groups are independently selected from phenyl and xylyl groups. In the resinous composition, the flame retardancy of the mixture per unit weight of phosphorus is greater than that of either triphenyl phosphate (TPP) or trimesityl phosphate (TMP) per se. <IMAGE> |
