Claims (2)

1. Способ стабилизации полиизопренового каучука, получаемого полимеризацией изопрена в среде углеводородного растворителя, включающий введение в раствор получаемого полимера раствора антиоксидантов аминного типа в органическом растворителе, отличающийся тем, что в качестве органического растворителя антиоксидантов используют C5, С6 алифатические углеводороды, содержащие олефиновый углеводород C5-C18 или их смеси в количестве 5 - 11 мас. %.1. A method of stabilizing polyisoprene rubber obtained by polymerization of isoprene in a hydrocarbon solvent medium, comprising introducing into the solution of the resulting polymer a solution of amine type antioxidants in an organic solvent, characterized in that C 5 , C 6 aliphatic hydrocarbons containing olefinic hydrocarbon are used as an organic solvent of antioxidants C 5 -C 18 or mixtures thereof in an amount of 5 to 11 wt. % 2. Способ по п. 1, отличающийся тем, что в качестве аминных антиоксидантов используют смесь п-фенилендиаминов: N-(1,3-диметилбутил)N'-фенил-п-фенилен-диамина с N-(1,3-диметилбутил)-N(4-кумилфенил)-п-фенилендиамином (I) или N-(l, 4-диметилпентил)-N'-фенил-п-фенилендиамином (II). 2. The method according to p. 1, characterized in that as the amine antioxidants using a mixture of p-phenylenediamines: N- (1,3-dimethylbutyl) N'-phenyl-p-phenylene-diamine with N- (1,3-dimethylbutyl ) -N (4-cumylphenyl) -p-phenylenediamine (I) or N- (l, 4-dimethylpentyl) -N'-phenyl-p-phenylenediamine (II).
