  • Unsaturated polylactone acrylates and derivatives thereof
    Patent number: 5557007
    Abstract: Novel unsaturated polylactone acrylates are produced by the reaction of an unsaturated polylactone, such as that produced in the reaction of a lactone with tetrahydrobenzyl alcohol, and a lower-alkyl acrylate under transesterification conditions. The unsaturated polylactone acrylate product may be subsequently epoxidized to form novel 3,4-epoxy polylactone acrylates.
    Type: Grant
    Filed: September 28, 1990
    Date of Patent: September 17, 1996
    Assignee: Union Carbide Chemicals & Plastics Technology Corporation
    Inventor: James P. Stanley
  • Acid viscosifier compositions
    Patent number: 4959432
    Abstract: Cationic, anionic and amphoteric polymers suitable for the preparation of acid viscosifier compositions and the acid viscosified compositions are provided. The polymers are water soluble or water dispersible and are based on acrylyl monomers having the stated ionic charge. They are capable of viscosifying acid solutions that have important use in recovery of gas and oil from subterranean formations.

  • Gelable acid viscosifiers
    Patent number: 4889887
    Abstract: Gelable acid compositions containing novel crosslinkable copolymers and the novel copolymers. The copolymers contain an N-(alkoxymethylene)acrylyl moiety. In addition there are provided gelable acid compositions containing a group of polyfunctional reactants that contain a plurality of --CH.sub.2 OH and/or --CH.sub.2 CH.sub.2 OH groups in the molecule.

  • Polysaccharides, methods for preparing such polysaccharides and fluids utilizing such polysaccharides
    Patent number: 4579942
    Abstract: Water-soluble polysaccharides, including cellulose ethers, containing pendent vicinal dihydroxy structure capable of cis geometry, which upon crosslinking with a polyvalent metal, have shear-thermal stability characteristics of at least about 30 at 250.degree. F., are useful in oilfield applications.
