Publication number: 20030166813Abstract: The &bgr;-hydroxy carbamate, ethylenically unsaturated monomer of the invention can be polymerized as a homopolymer or copolymerized with other monomers. The polymerization can be carried out in an aqueous medium. The &bgr;-hydroxy carbamate monomer is polymerized to form water-soluble homopolymers or, if polymerized as a mixture with one or more comonomers, copolymers that are soluble, emulsifiable, or dispersible in water. The &bgr;-hydroxy carbamate monomer can be used as a replacement monomer for acrylamide.Type: ApplicationFiled: March 19, 2003Publication date: September 4, 2003Inventors: Walter H. Ohrbom, Patricia A. Herrel

Patent number: 6596831Abstract: Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of vinylic and dicarboxylic monomers such as vinyl acetate or vinyl alcohol and maleic anhydride, itaconic anhydride or citraconic anhydride, or combinations thereof. Free radical polymerization is used in the synthesis of the polymers, which are then hydrolyzed to replace ester groups with alcohol groups. The polymers may be complexed with ions and/or mixed with fertilizers or seed to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly, to seeds, to fertilizer, or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.Type: GrantFiled: December 18, 2001Date of Patent: July 22, 2003Inventors: John Larry Sanders, James Michael Kimmerly, Grigory Mazo

Patent number: 6566549Abstract: A continuous process for oligomers which do not contain, as polymerized units, carboxylic acid-containing monomers and their salts, including the steps of: (1) forming a reaction mixture, substantially free of carboxylic acid-containing monomers and their salts, containing: (i) 0.5 to 99.95% by weight of the reaction mixture of at least one ethylenically unsaturated monomer; and (ii) 0.05 to 25% by weight, based on the weight of the ethylenically unsaturated monomer, of at least one free-radical initiator; and (2) continuously passing the reaction mixture through a heated zone wherein the reaction mixture is maintained at a temperature of at least 150° C. and a pressure of at least 30 bars for from 0.1 seconds to 4 minutes to form terminally-unsaturated oligomers. In addition, processes for forming oligomers of vinyl acetate and oligomers of vinyl alcohol are disclosed. Mixtures of fully saturated and terminally unsaturated oligomers are also disclosed.Type: GrantFiled: December 15, 1998Date of Patent: May 20, 2003Assignee: Rohm and Haas CompanyInventors: Gary David Greenblatt, Barry Clifford Lange, Michael Damian Bowe, Richard Foster Merritt, Robert Wilczynski, Gary Robert Larson, Lori Marie Petrovich, David William Whitman
