    摘要: A novel stabilizing mixture composed of 1 1,3,5-tris 2-[3-(3-t-butyl-4-hydroxy-5-methyl-phenyl)-propionyloxyl] ethyl isocyanuric acid (I) and at least one sulfur-containing compound (II) selected from compounds represented by the general formulas (II-1) and (II-2): ##STR1## wherein R.sub.1 is an alkyl group having 4 to 20 carbon atoms, and ##STR2## wherein R.sub.2 is an alkyl group having 3 to 18 carbon atoms, and R.sub.3 and R.sub.4 each independently is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, is useful as a stabilizer for synthetic resins.

    摘要: Phosphorus-containing compounds of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are each a hydrogen atom or a lower alkyl group, and R.sup.3 is a lower alkyl or phenyl group. These compounds may be used as stabilizers against the action of heat, light and oxygen for organic substances and especially polyolefin resins. These phosphorus-containing compounds may be used in conjunction with other stabilizers such phenol-type and sulfur-containing antioxidants, especially in polyolefin resin compositions to produce a polyolefin resin composition having excellent resistance to light, heat and oxygen. The present invention also relates to a method of producing the compounds of the aforementioned formula by reacting ##STR2## with a disubstituted phosphonate of the formula ##STR3## wherein R.sup.1, R.sup.2 and R.sup.3 are as defined above.
