METHOD OF SYNTHESIS OF ELASTOMER STABILIZING AGENT Russian patent published in 1996 - IPC

Abstract RU 2064924 C1

FIELD: polymers, chemical technology. SUBSTANCE: invention relates to synthesis of substituted amine-base stabilizing agents. Method involves alkylation of diphenylamine with vinylaromatic compounds at heating in the presence of catalyst Friedel-Crafts. Alkylation is carried out in the presence of N,N-diethylhydroxylamine or 4-hydroxydiphenylamine, or alkylphenol at chain length C8-C12 at dose 0.01-50.00 wt.-% as measured for diphenylamine. Stabilizing agents can be used for synthesis of rubber, rubber-base vulcanizates and other polymers. EFFECT: simplified technology of synthesis.
