  • Method of making graft copolymers from sodium poly(aspartate) and the resulting graft copolymer
    Patent number: 8202946
    Abstract: A variety of graft copolymers can be formed sodium poly(aspartate) with a wide variety of monomers in an aqueous medium by the use of grafting method in the presence of radical initiator at a temperature of from about five degrees Centigrade to about 100 degrees Centigrade. Graft copolymers at high conversion with molecular weight up to millions can be prepared using this method.
    Type: Grant
    Filed: May 2, 2011
    Date of Patent: June 19, 2012
    Assignee: NanoChem Solutions, Inc.
    Inventors: Damodar R. Patil, Laiduien G. Fan, Joseph C. Fan, Jiangping Yu
