  • Preparation of novel homo- and copolymers using atom transfer radical polymerization
    Patent number: 5945491
    Abstract: The present invention is directed to a process of atom (or group) transfer radical polymerization for the synthesis of novel homopolymer or a block or graft copolymer, optionally containing at least one polar group, with well defined molecular architecture and narrow polydispersity index, in the presence of an initiating system comprising (i) an initiator having a radically transferrable atom or group, (ii) a transition metal compound, and (iii) a ligand; the present invention is also directed to the synthesis of a macromolecule having at least two halogen groups which can be used as a macroinitiator component (i) to subsequently form a block or graft copolymer by an atom or group transfer radical polymerization process; the present invention is also directed to a process of atom or group transfer radical polymerization for the synthesis of a branched or hyperbranched polymer; in addition, the present invention is directed to a process of atom or group transfer radical polymerization for the synthesis of a ma

    Filed: September 30, 1997
    Date of Patent: August 31, 1999
    Assignee: Carnegie-Mellon University
    Inventors: Krzysztof Matyjaszewski, Simion Coca, Scott G. Gaynor, Yoshiki Nakagawa, Seong Mu Jo
