Control agents for living-type free radical polymerization, methods of polymerizing, emulsions and polymers with same

Living type free radical polymerization of a broad kind of monomer is provided with the control agent which has nitrogen * nitrogen combination combined with a チオカルボニル part in electronic share. These control agents offer the characteristic outstanding to the characteristic and/or the monomer which may polymerize of control of polymerization, and/or the obtained polymer. In some enforcement forms, a bulky basis carries out under 垂 from the チオカルボニル part by which the control agent was activated. A multifunction control agent offers an opportunity to form structurally unique various polymer containing a block co-polymer, a star shape, and the polymer that hyper-branched.
