Abstract:
The invention provides polyester polyol compositions, useful as components of polyurethane and polyisocyanurate polymers, prduced 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.
Abstract:
A method for preparing a microemulsion is disclosed which employs a method based upon identification of the phase behavior of a plurality of components comprising the microemulsion. Further disclosed is a microemulsion composition comprising a first component, coupling agent, and surfactant.
