Preparation of polyalkoxyamines by the reaction of a monoalkoxyamine with a polyunsaturated compound in the presence of a solvent at 0-90 deg. C, followed by evaporation of the solvent. - Preparation of polyalkoxyamines by the reaction, under nitrogen, of a monoalkoxyamine of formula (I) with a polyunsaturated compound Z-(CH=CH2)n (II), optionally in the presence of a solvent such as ethanol, an aromatic chlorinated compound, ether or an aprotic polar compound and at 0-90 deg. C: - R1 = 1-3C alkyl; - R2 = H, 1 - 8C alkyl, phenyl, or an alkali metal Li, Na or K, or NH4+, NBu4+, or NHBu3+; - Z = aryl group or a radical Z1-(X-C(O))n; - Z1 = poly-functional structure such as a polyol; - X = O ,N (attached to a carbyl group or H) or S; - n = 2 or more. - The molar ratio of (I) to (II) is 1.5 - 1.5n, more preferably n - 1.25n. - Optionally, this is followed by evaporation of the solvent:.
