FIELD: chemistry.
SUBSTANCE: invention relates to an amine antioxidant for rubber, which is a mixture of isomers of N-isononyl-N'-phenyl-p-phenylenediamine (9PPDA) in liquid form, and a method for production thereof. A rubber stabiliser in powder form is obtained from 9PPDA in liquid form. The amine antioxidant has high solubility, which makes it easier to prepare working antioxidant solutions for filling polymerisates of solution-type rubber in the cold period, and also has an additional function as an antiozonant.
EFFECT: method of producing an amine antioxidant reduces the alkylation reaction time and unit consumption of alcohol.
