摘要:
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.

Disclosed are toluate ester compositions and their use as solvent, plasticizers, extender and/or diluents in binder formulations, a method of producing such ester compositions, as well as polymer compositions containing such liquid ester compositions. Also disclosed is a method of making toluate based esters by reacting methyl-p-toluate with ethylene glycol, diethylene or triethylene glycol, butanediol, etc.
摘要:
This invention relates to toluate ester compositions and their use as solvent, plasticizers, extender and/or diluents in binder formulations, a method of producing such ester compositions, as well as polymer compositions containing such liquid ester compositions. The method of making toluate based esters by reacting methyl-p-toluate with ethylene glycol, diethylene or triethylene glycol, butanediol, etc. More particularly, this invention relates to the mono- or di-ester of methyl toluic acid with a diol containing 2 to 6 carbon atoms that are low viscosity liquids at 25° C. The most common polymer that employs plasticizer is polyvinyl chloride (PVC). Typical amounts of plasticizer in PVC are from about 3 wt. % to about 50 wt. %. Phenolic resins generally require solvents, diluents and/or extenders that reduce the volatility and viscosity of the resin, especially when it is used in building and automotive products. Typical amounts of solvent are from about 5 wt. % to about 65 wt. %.

The present invention relates to the manufacture of alkyl p-toluates from an alkyl p-toluic acid ester and a mono-functional, branched, linear or cyclic medium chain length alkyl alcohol, and their use as a plasticizer in polymers. Additionally, the present invention relates to articles and materials comprising such alkyl p-toluates.
