  • Polymerization in the presence of a &bgr;-substituted nitroxide radical
    Patent number: 6255448
    Abstract: The invention relates to a process for the polymerization or copolymerization of at least one monomer which is polymerizable by the radical route in the presence of a stable free radical from the nitroxide family. The stable free radical is &bgr;-substituted and provides excellent control of polydispersity while ensuring a better rate of polymerization or copolymerization, if they are compared with the stable free radicals used in the prior art.
