ABSTRACT:
A stabilizer mixture containing(A) a sterically hindered amine compound, and(B) two different compounds selected from the group consisting of an organic salt of Zn, an inorganic salt of Zn, an organic salt of Mg and an inorganic salt of Mg;the weight ratio of the two different compounds being 1:10 to 10:1;with the provisos that(1) the stabilizer mixture is essentially free of perchloric acid, and(2) the two compounds in component (B) are different from the combination ZnO and Zn stearate and the combination ZnO and hydrotalcite;is useful for stabilizing an organic material, in particular a polyolefin, against degradation induced by light, heat or oxidation.
