  • Patent number: 7772340
    Abstract: A subject-matter of the invention is alkoxyamines resulting from ?-phosphorated nitroxides corresponding to the formula: in which R represents an alkyl radical having a number of carbon atoms ranging from 1 to 3, R1 represents a hydrogen atom or a residue: in which R3 represents an alkyl radical having a number of carbon atoms ranging from 1 to 20, and R2 represents a hydrogen atom, an alkyl radical having a number of carbon atoms ranging from 1 to 8, a phenyl radical, an alkali metal, such as Li, Na or K, H4N+, Bu4N+ or Bu3HN+, exhibiting a kinetic dissociation constant kd, measured at 120° C. by EPR, of greater than 0.05 s?1. These compounds can be used as initiators for the (co)polymerizations of at least one monomer which can be polymerized by the radical route.

  • Publication number: 20090221850
    Abstract: The present invention relates to a novel process for preparing alkoxyamines from a nitroxide and a dithiocarbamate by photolysis reaction. This process, which does not generate effluent containing metals, may be carried out in batch or in continuous mode and takes place at a lower temperature than the known processes for synthesizing alkoxyamines.
