  • Polymeric micelle compositions with improved stability and methods of making thereof
    Patent number: 7879317
    Abstract: Polymeric compositions capable of forming stable micelles in an aqueous solution, comprising an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block, and a polylactic acid derivative wherein one end of the polylactic acid is covalently bound to at least one carboxyl group. The carboxyl group of the polylactic acid derivative may be fixed with a di- or tri-valent metal ion, obtained by adding the di- or tri-valent metal ion to the polymeric composition.
    Type: Grant
    Filed: October 17, 2002
    Date of Patent: February 1, 2011
    Assignee: Samyang Corporation
    Inventors: Min-Hyo Seo, Sa-Won Lee, Hee-Jo Kim, Jeong-Kyung Kim, Myung-Han Huyn, Jeong-il Yu, Bong-Oh Kim
