Patent number: 8455591Abstract: A polyol composition comprising a polyol (a) and resin fine particles (b) dispersed in the polyol (a), and a method for producing the polyol composition are provided, wherein the resin fine particles (b) are particles such that an arithmetic standard deviation by volume of a particle size distribution of the particles, derived from respective values in 85 divisions of a range of 0.020 to 2000 ?m determined by a laser diffraction/scattering particle size distribution analyzer, is not more than 0.6. A resin fine particle-dispersed polyol composition that, even if the resin particles dispersed in the polyol have a small particle diameter, allows the production of a polyurethane resin having an excellent mechanical strength such as elongation at break, and a method for producing the same, are provided.Type: GrantFiled: August 16, 2011Date of Patent: June 4, 2013Assignee: Sanyo Chemical Industries, Ltd.Inventors: Shigekuni Nakada, Hiroyuki Watanabe, Takayuki Tsuji, Hiroki Mori

Publication number: 20130042659Abstract: The invention provides polyester polyol compositions and resin blends, useful as components of polyurethane and polyisocyanurate polymers, produced from cyclohexane oxidation reaction byproducts, such as water extracts and non-volatile distillation residues from the reaction. Such byproducts of industrial processes for preparation of adipic acid and caprolactam, important intermediates in the production of various types of nylon, have hitherto largely been used only as fuels. The present invention provides value-added products, methods for making, and methods for using the byproduct-derived polyester polyol compositions. For example, the invention provides polyurethane (PU) and/or polyisocyanurate (PIR) polymers made using the polyol compositions and polyfunctional isocyanates. The PU and PIR polymers can be used as adhesives, binders (e.g., for wood fibers), coatings (e.g., for controlled release fertilizers), and foams.Type: ApplicationFiled: June 11, 2012Publication date: February 21, 2013Applicant: INVISTA North America S.a r.lInventors: Richard P.
