Patent number: 8106148Abstract: A series of resins were synthesized using a range of bio-based materials to control the molecular architecture, and therefore the properties, of the inventive resins. The utility of these resins was demonstrated in the formulation of powder coatings, such as ?-hydroxy amide crosslinked and hybrid types. Generally, the bio-based resins flowed out on heating faster than conventional petrochemically-based resins, allowing the use of lower temperatures in the curing oven than is typically possible and a more active catalyst system, especially in the carboxylic acid-epoxy crosslinked hybrid coatings formulations.Type: GrantFiled: March 20, 2006Date of Patent: January 31, 2012Assignee: Battelle Memorial InstituteInventors: Bhima R. Vijayendran, Jerry L. King, II, Katherine P. Mitchell, Michael C. Clingerman, Jeffrey T. Cafmeyer

Publication number: 20110028314Abstract: Absorbent hydrogels are formed by reacting a protein meal base, a radical initiator and a polymerizable monomer. Optionally, a cross-linking agent and/or a radical accelerant, such as tetramethylethylenediamine (TMEDA) or sodium bisulfite (NaHSO3), is also added to the mixture. Preferably, the radical initiator is ammonium persulfate (APS) or potassium persulfate (KPS), and the cross-linking agent is preferably trifunctional trimethylolpropane trimethacrylate (TMPTMA) or methylene bis acrylamide (MBA). The polymerizable monomer is preferably acrylic acid, or a combination of acrylic acid and acrylamide. The as-formed hydrogel is washed in order to extract non-reactant components from the gel and then dried. The resultant absorbent and superabsorbent hydrogels have high water uptake ratios, and can be utilized for a variety of applications.Type: ApplicationFiled: February 23, 2009Publication date: February 3, 2011Applicant: BATTELLE MEMORIAL INSTITUTEInventors: Herman P Benecke, Bhima R Vijayendran, Kevin B Spahr
