FIELD: chemistry.
SUBSTANCE: present invention relates to a composition, which is a liquid at ambient conditions, for stabilising polymers and method for stabilisation of the said composition ingredients, which may be used in chemical industry. The proposed composition comprises an amine of formula
where x = 1 to 3, R1 selected from H and C1-C6-alkyl, R2 is a C1-C30-alkyl, and at least two phosphites of formula
where R3, R4 and R5 are selected from C4-C5-alkylsubstituted C6-C18-aryls. The method for stabilisation includes addition of the said amine in the amount of 0.01 to 3 wt %.
EFFECT: composition for stabilising polymers.
