  • Hybrid copolymer compositions
    Patent number: 9109068
    Abstract: Hybrid copolymer compositions include a hybrid copolymer including at least one ethylenically unsaturated monomer and a naturally derived hydroxyl containing chain transfer agent as an end group; and a hybrid synthetic copolymer including one or more synthetic polymers derived from the at least one ethylenically unsaturated monomer with at least one initiator fragment as an end group. The hybrid copolymer composition may be prepared as a scale inhibiting composition. Methods of preparing a hybrid copolymer are also included.
    Type: Grant
    Filed: July 30, 2010
    Date of Patent: August 18, 2015
    Assignee: AKZO NOBEL N.V.
    Inventors: Klin A. Rodrigues, Matthew M. Vanderhoof, Allen M. Carrier, Jannifer Sanders
  • Graft copolymers
    Publication number: 20130137799
    Abstract: Anionic graft copolymers and scale inhibition compositions including the anionic graft copolymers in which the anionic graft copolymers include a natural component grafted with an ethylenically unsaturated anionic monomer where the anionic graft copolymer includes 1 or more reacted anhydroglucose units per every 100 anhydroglucose units in the anionic graft copolymer.
