An organic polymer, such as polyolefin, unsaturated elastomer, copolymer of mono, diolefin, and vinyl monomer, copolymer of polystyrene and styrene, polymer of - , -unsaturated acid and its derivatives, etc., is stabilized by the addition of 0.05-2 wt.% of compd. (I) and 0.001-1 wt.% of phenolic compd., where R1 = H, C1-C23 alkyl, or C2-C23 alkenyl substituted 1-5 ydroxy gp.; R2 = H, methyl, or phenyl; R3 = H or methyl; n = 0-4; Me = metal of group I, II, and III, Zn, Cd, Sn, Pb, Ti, Br, or V; and m = valency of metal.
