  • Amino acid and carbohydrate polymers for use in soil retention, water conservation, water clarification, and dust control
    Publication number: 20070085055
    Abstract: Water-soluble amino acid copolymers, modified polysaccharides, acrylamide polymers, and combinations thereof, are described, for uses including flocculation of solids, particularly flocculation of soil, such as in an agricultural setting. Also described are methods of preparing selected amino acid copolymers and modified polysaccharides.

  • Copolymers of amino acids and methods of their production
    Publication number: 20070015901
    Abstract: Disclosed are copolymers based on aspartic acid or its precursor molecules and methods of their production. The copolymers are water-soluble over a wide range of composition and molecular weight. Their preparation involves conversion of a polysuccinimide to copolymers of defined composition, containing aspartate and succinimide residues and/or residues of asparagine. In particular, the copolymers include water-soluble terpolymers of aspartate, asparagine, and succinimide.

  • Preparation of high molecular weight polysuccinimides
    Publication number: 20060205918
    Abstract: Described are methods of production of polysuccinimides having molecular weights up to 200,000 daltons and higher. The polysuccinimides of the invention are essentially unbranched and uncrosslinked. They can be modified by crosslinking, ring-opening, and/or other functionalization, if desired, to form gelling materials of superior performance. The high Mw polysuccinimides are also particularly useful as thickening agents, viscosity modifiers, emollients, humectants and in other applications that are known in the art to be serviced most effectively by molecules of higher molecular weight.
