FIELD: polymer materials.
SUBSTANCE: invention relates to stabilizer mixture used for stabilizing polyolefin against destruction initiated by visible light, heat, or oxidation and to thus stabilized polyolefin. Stabilizer mixture comprises spatially hindered amine compound and polymer containing polar residues, weight ratio of the two compounds being between 20:1 and 1:20, respectively, provided that (i) polymer cannot be the same compound as hindered amine compound and does not contain groups of formula (1) or (II): 
. Where G represents hydrogen atom or methyl and G1 and G2, independently of each other, each represents hydrogen atom or methyl or they together form =O; and (ii) polymer cannot contain acidic hydrogen atom.
EFFECT: considerable increased efficiency of stabilizer composition.
