  • Patent number: 8106148
    Abstract: 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.

  • Publication number: 20110212396
    Abstract: Disclosed are amorphous polyesters that contain only renewable resources designed for emulsion aggregation toner fabrication. The amorphous polyesters may be obtained from the mixture of three different monomers: 1,4:3,6-dianhydro-D-sorbitol (isosorbide), nonanedioic acid (azelaic acid), and butanedioic acid (succinic acid). Different polymer properties may be achieved depending on the ratio of these three monomers. By altering the ratio, polymers of high to low acid value can be obtained, as well as different ranges of glass transition temperatures.

  • Patent number: 7960496
    Abstract: Disclosed herein is a novel stabilizer for preparing a polymer polyol, which is used to prepare polyurethane foam having improved physical properties. The stabilizer is prepared by allowing maleic anhydride to react with a polyether polyol, having an OH functionality of 3-8 and a molecular weight of 3,000-15,000, and then adding ethylene oxide to the reaction solution. Because the molecular weight and functionality of the stabilizer are increased through aging and dimerization, the stabilizer has a high molecular weight of 5,000-30,000, a high OH functionality of 6-10 and a viscosity of 3,000-15,000 cps/25° C. A polymer polyol derived from the stabilizer has low viscosity compared to those of prior products and contributes to the improvement in the physical properties of the resulting polyurethane foam.
