  • Amphipathic graft copolymer pesticide formulation compositions and methods of their use
    Patent number: 5787686
    Abstract: The present invention further provides a substantially non-aqueous agricultural pesticide concentrate formulation of a non-ionic surfactant and a amphipathic graft copolymer composition in admixture with a water-insoluble organic agricultural pesticide which concentrate formulation can be easily diluted with water to form non-settling, freeze-thaw stable formulations.The present invention further provides methods for the use of water-diluted agricultural pesticide concentrate formulations of the above non-ionic surfactant concentrate formulations in the kill and control of agricultural pest.
    Type: Grant
    Filed: January 21, 1997
    Date of Patent: August 4, 1998
    Assignee: The Dow Chemical Company
    Inventors: Craig J. Bott, Dale M. Pickelman, Ritchie A. Wessling

  • Amphipathic graft copolymers and copolymer compositions and methods of making
    Patent number: 5753766
    Abstract: The present invention provides amphipathic graft copolymers which comprises a hydrophobic polymer portion to which is grafted at least one amphipathic polymer portion containing pH independent ionic groups. The amphipathic graft copolymers can be prepared employing a procedure which comprises polymerizing at least two hydrophobic monomers, wherein at least one of the monomers is a graftable monomer, and at least one hydrophilic monomer, including at least one anionic and/or cationic pH independent ionic monomer, or a post reactive non-ionic monomer that can be converted to a pH independent ionic derivative, in a reaction medium and recovering the thus prepared amphipathic graft copolymer. Stable, substantially non-aqueous solution compositions of said amphipathic graft copolymer containing less than 15 percent by weight water are also provided.
