Patent number: 8097119Abstract: Epoxy adhesive compositions containing a rubber-modified epoxy resin contain a bisphenol. The bisphenol can be pre-reacted with the rubber-modified epoxy resin to advance the resin. The adhesives are resistant to thermal degradation as can occur in so-called “overbake” conditions, in which the adhesive is heated to high temperatures for prolonged periods of time. In addition, expanded microballoons are included in epoxy structural adhesives to promote a desired fracture mode.Type: GrantFiled: April 9, 2008Date of Patent: January 17, 2012Assignee: Dow Global Technologies LLCInventors: Glenn G.

Patent number: 8058389Abstract: Brominated polybutadiene polymers are recovered from a bromination reaction solution by forming the solution into droplets, thermally stripping the solvent from the droplets, and then washing the resulting particles. The washed particles are then recovered from the washing liquid. The droplets can be dispersed into a gaseous medium such as air and then transferred into a nonsolvent liquid for washing, or can be formed directly into the nonsolvent liquid. The process forms a particulate polymer material that is easily filterable and has low levels of volatile impurities and inorganic salts. Brominated polybutadiene polymers recovered in this manner are often very thermally stable.Type: GrantFiled: June 26, 2008Date of Patent: November 15, 2011Assignee: Dow Global Technologies LLC.Inventors: Ronald B. Leng, Avani M. Patel, Brian D. Scherzer, Derrick G. Wetters, Douglas C. Greminger

Patent number: 7939298Abstract: Specific oxygen uptake (OUR) is used as a process control parameter in fermentation processes. OUR is determined during at least the production phase of a fermentation process, and process parameters are adjusted to maintain the OUR within desired ranges. The invention is particularly applicable when the fermentation is conducted using a microorganism having a natural PDC pathway that has been disrupted so that it no longer functions. Microorganisms of this sort often produce poorly under strictly anaerobic conditions. Microaeration controlled by monitoring OUR allows the performance of the microorganism to be optimized.Type: GrantFiled: February 14, 2007Date of Patent: May 10, 2011Assignee: Cargill Inc.Inventors: Pim Van Hoek, Aristos Aristidou, Brian Rush
