Alkoxyamines derived from beta-phosphorylated nitroxides, and use thereof for preparing polymerized or non-polymerized mono- or polyalkoxyamines

1. A method for preparing a polymerised or non-polymerized mono- or polyalkoxyamine comprising reacting an alkoxyamine of formula (I):

in which A represents a hydroxyl radical, a radical R 1 O— in which R 1 represents a linear or branched alkyl residue containing a number of carbon atoms ranging from 1 to 6; a radical MeO— in which Me represents an alkali metal; an H4N + —, BN 4 N + — or Bu 3 HN + — radical; a chlorine atom; R represents a hydrogen atom or a methyl radical; M is a free-radical-polymerizable vinyl monomer sequence; n is an integer that may be equal to 0 or 1; to form a polymerised or nonpolymerized mono- or polyalkoxyamine of the formula (II):

in which R and n have the same meaning as in formula (I); x is an integer equal to 1 or 2; Z represents a mono- or polyfunctional structure chosen from alcohols, polyols, amines, polyamines, epoxides, polyepoxides, esters, polyesters, amides, polyamides, imines, polyimines, polycarbonates, polyurethanes or silicones.

2. The method of claim 1 wherein said alkali metal Me is selected from the group consisting of Li, Na, K, and mixtures thereof.

3. The method of claim 1 in which M is styrene, substituted styrenes, dienes, acrylic monomers, methacrylic monomers, acrylonitrile, acrylamide and its derivatives, vinylpyrrolidinone or a mixture of at least two above mentioned monomers.

4. The method of claim 3 wherein the acrylic monomer is selected from the group consisting of acrylic acid or alkyl acrylates and mixtures thereof; and the methacrylic monomer is selected from the group consisting of methacrylic acid or alkyl methacrylates and mixtures thereof.

5. The method of claim 1 wherein said method forms allyl 2-[N-tert-butyl-N-(1-diethoxyphosphoryl-2,2-dimethylpropyl)aminoxy]propionate:

6. The method of claim 1 wherein said method forms N-allyl-2-[N-tert-butyl-N -(1-diethoxyphosphoryl-2,2-dimethylpropyl)aminoxy]propionamide:

7. The method of claim 1 wherein said method forms a dialkoxyamine of formula:

8. The method of claim 1 wherein said method forms a compound of formula (II) in which x=1, n=0, R=CH 3 and Z=CH 3 (OCH 2 CH 2 ) p O—.

9. The method of claim 1 wherein Z is selected from the group consisting of CH 2 ═CH—CH 2 —O—, CH 2 ═CH—CH 2 —NH—, CH 3 —(OCH 2 CH 2 ) p —O—, and —O—(CH 2 ) q —O—, wherein p and q are independently integers at least equal to one.
