Abstract

The invention relates to the use of alkoxyamines of formula (I): for the preparation of polymerized or non-polymerized mono- or polyalkoxyamines of formula (II):

1 . An alkoxyamine of formula (I):  
     
       
         
         
             
             
         
       
     
     in which A is selected from a hydroxyl radical; a radical MeO— in which Me represents an alkali metal; a H4N + — radical, a Bu 4 N + — radical; a Bu 3 HN + — radical; or 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, with the proviso that when A is selected from OH or CH 3  and R is H, n is not 0,.  
   
   
       2 . The alkoxyamine of  claim 1  in which M is selected from styrene, substituted styrenes, dienes, acrylic monomers, methacrylic monomers, acrylonitrile, acrylamide and its derivatives, vinylpyrrolidinone or a mixture of at least two abovementioned monomers.  
   
   
       3 . The alkoxyamine of  claim 2  wherein the acrylic monomer is selected from the group consisting of acrylic acid or alkyl acrylates and mixtures thereof.  
   
   
       4 . The alkoxyamine of  claim 1  wherein said alkali metal Me is selected from the group consisting of Li, Na, K, or mixtures thereof.  
   
   
       5 . The alkoxyamine of  claim 1  wherein said alkoxyamine is 2-[N-tert-Butyl-N-(1-diethoxyphosphoryl-2,2-dimethylpropyl)aminoxy]propionic acid:  
     
       
         
         
             
             
         
       
     
   
   
       6 . The alkoxyamine of  claim 1  wherein said alkoxyamine is 2-[N-tert-Butyl-N-(1-diethoxyphosphoryl-2,2-dimethylpropyl)aminoxy]propionyl chloride:  
     
       
         
         
             
             
         
       
     
   
   
       7 . The alkoxyamine of  claim 1  wherein said alkoxyamine is 2-Methyl-2-[N-tert-butyl-N-(1-diethoxyphosphoryl-2,2-dimethylpropyl)aminoxy]propionic acid:  
     
       
         
         
             
             
         
       
     
   
   
       8 . The alkoxyamine of  claim 1  wherein said alkoxyamine is 2-Methyl-2-[N-tert-butyl-N-(1-diethoxyphosphoryl-2,2-dimethylpropyl)aminoxy]propionyl chloride:  
     
       
         
         
             
             
         
       
     
   
   
       9 - 17 . (canceled)  
   
   
       18 . The alkoxyamine of  claim 2  wherein the methacrylic monomer is selected from the group consisting of methacrylic acid or alkyl methacrylates and mixtures thereof.
