| abstract | A product obtainable by (1) reacting a compound of the formula (Α) with a compound of the formula (β) in a stoichiometric ratio to obtain a compound of the formula (γ); (2) reacting the compound of the formula (β) with the compound of the formula (γ) in a molar ratio of 0.4:1 to 0.75:1; (3) reacting the end groups of the formula (δ) being present in the product of the reaction (2) with e.g. dibutylamine in a molar ratio of 2:1.7 to 2:3; the reactions (1) to (3) being carried out in an organic solvent in the presence of an inorganic base; and (4) transferring the groups of the formula being present in the product of the reaction (3) to groups of the formula, said transfer being carried out by reacting the product of the reaction (3) with a hydroperoxide in a hydrocarbon solvent in the presence of a peroxide decomposing catalyst; R1 is in particular a hydrocarbyl radical, B is e.g. N-(2,2,6,6-tetramethyl-4-piperidyl)-butylamino, R is e.g. 2,2,6,6-tetramethyl-4-piperidyl and R2 is e.g. hexamethylene. |
