    摘要： A process for the preparation of a product corresponding to the formula (I)
    wherein n is a number from 2 to 50; the radicals R 1 are for example 2,2,6,6-tetramethyl-4-piperidyl, R 2 is for example hexamethylene and E is for example t-octylamino; which comprises

    a) reacting a compound of the formula (A)
    with a compound of the formula (B)
    in a molar ratio of 1:1.7 to 1:4; and
    b) reacting the product obtained in a) with a compound of the formula (C)
    to obtain the product corresponding to the formula (I), the molar ratio of the compound of the formula (C) to the compound of the formula (A) being 2:1 to 1:5; the reactions a) and b) being carried out in an organic solvent, in the presence of an inorganic base and in an inert atmosphere.
