Patent number: 6818686Abstract: The invention relates to a water based polymer composition comprising a biopolymer and a synthetic polymer resin. The biopolymer results from a mechanical thermoplastic processing of a polysaccharide and/or protein starting material using shear forces in the presence of a crosslinking agent. The synthetic polymer resin consists of a water based hydrophilic resin and/or hydrophilic/hydrophobic resin. These compositions have a good storage stability. They are intended for the production of coatings with fair properties.Type: GrantFiled: July 8, 2002Date of Patent: November 16, 2004Assignee: UCB, S.A.Inventors: Marc Colpaert, Dirk Bontinck, Patrice Roose

Patent number: 6800593Abstract: Disclosed is a hydrophilic, water soluble polymer concentrate for addition to aqueous liquids to enhance the properties thereof, particularly to increase the viscosity or decrease the fluid loss of well drilling and servicing fluids, the concentrate comprising a hydrophobic, water insoluble liquid, an organophilic clay suspension agent, the water soluble polymer, and a stabilizing agent comprising one or more acids in an amount from about 0.001% to about 1.5%, one or more anionic surfactants in an amount from about 0.001% to about 1.0%, one or more nonionic surfactants in an amount from 0.001% to about 0.625% and, from about 0% to about 0.75% of one or more water soluble organic liquids, wherein the total concentration of the stabilizing agent is from about 0.1% to about 2.5%, these percentages being based on the weight of the concentrate.Type: GrantFiled: June 19, 2002Date of Patent: October 5, 2004Assignee: Texas United Chemical Company, LLC.Inventors: James W. Dobson, Jr., Shauna Leigh Hayden, Carolina Trejo Rangel
