Patent number: 9102831Abstract: Cross-linked zein articles are prepared by a melt process where zein is mixed with polyethylene maleic anhdyride. The melt processing can be conducted as a batch process (e.g., as in a torque rheometer) or as a continuous process (e.g., as in reactive extrusion using a screw extruder). This process provides a zein article that has reduced solubility in acetic acid (a solvent that normally dissolves unaltered zein) and/or increased tensile strength.Type: GrantFiled: September 11, 2012Date of Patent: August 11, 2015Assignee: The United States of America, as represented by The Secretary of AgricultureInventor: Gordon W. Selling

Patent number: 7838617Abstract: Commercial spandex can be prepared with greater efficiency, improved consistency and at lower costs from a high-solids content polyurethaneurea polymer solution. The polyurethaneurea is prepared using a combination of 4,4?-MDI and 2,4?-MDI, and an amount of chain extenders and chain terminators such that the polymer solution, prior to spinning, is highly soluble and has an appropriate pre-spun IV and primary amine content. Such spandex fibers, and the fabrics and garments comprising them, have good dyeability and colorfastness, as well as other desirable characteristics.Type: GrantFiled: November 3, 2004Date of Patent: November 23, 2010Assignee: INVISTA North America s.àr.l.Inventors: Nathan E. Houser, Gordon W. Selling, Beverly Jean Selle, Steven Peter Pardini, Robert Dewhurst, Elizabeth Todd Singewald

Patent number: 7771528Abstract: Zein articles are prepared by a melt process where zein is mixed with glyoxal and an inorganic base solution at temperatures above about 40° C. The melt processing can take as a batch process (e.g., as in a torque rheometer) or in a continuous process (e.g., as in reaction extrusion using a screw extruder). This process provides a zein article that has greatly reduced solubility in most of the standard organic solvents that will dissolve unaltered zein.Type: GrantFiled: August 16, 2007Date of Patent: August 10, 2010Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Gordon W. Selling, Kristen K. Woods
