FIELD: organic chemistry; production of rubbers, rubber-based vulcanizates and other polymer materials. SUBSTANCE: proposed stabilizing agents for production of elastomers are based on substituted amines and produced by alkylation of diphenyl amine with vinylaromatic compounds, under heating conditions, in presence of Friedel-Crafts catalyst. Alkylation is carried out in presence of N,N-diethylhydroxyl amine, or 4-oxydiphenyl amine, or alkyl phenol having chain length C-Ctaken in amount 0.01-50.00 wt.% based on diphenyl amin. EFFECT: simplified production process; easier use. |
