Patent ID: 7199214

Claim:
Process for the preparation of polyalkoxyamines having functional groups: in which m is an integer greater than or equal to 2 and less than or equal to n, which comprises reacting at least one monoalkoxyamine(s) of formula (I) in which R 1 represents a linear or branched alkyl radical having a number of carbon atoms ranging from 1 to 3 and R 2 represents a hydrogen atom, a liner or branched alkyl radical having a number of carbon atoms ranging from 1 to 8, a phenyl radical, an alkali metal, selected from the group consisting of Li, Na or K, or an ammonium ion, selected from the group consisting of NH 4 + , NBu 4 + or NHBu 3 + ; with at least one polyunsaturated compound of formula (II): in which Z is an aryl group or Z 1 -[X—C(O)] n where Z 1 represents a polyfunctional structure, X is an oxygen atom, a nitrogen atom carrying a carbonaceous group, a hydrogen atom, or a sulphur atom, and n is an integer greater than or equal to 2, at a reaction temperature f between about 0 and 90° C., the molar ratio of monoalkoxyamine(s) of formula (I) to polyunsaturated compound(s) of formula (II) being between 1.5 and 1.5 n.
