Novel stabilizers for organic materials subject to degradation, 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes are prepared by the reaction of substituted-phenylphosphorodichloridites, water and amines. The 2,4,6-tris(substituted phenoxy)-1,3,5,2,4,6-trioxatriphosphorinanes, form effective stabilizer combinations with hindered and partly hindered phenols such as hydroxyphenylalkyleneyl isocyanurates, particularly when used in polymers, polyolefins, for example.
