摘要:
The invention provides for new flame retardant non-furan dicarboxylic acid (FDCA) based polyols; oligomers and polymers made from these new polyols with flame retardation properties; and methods of using them as a part or all of the flame retardation composition/material, such as foams and binders.
摘要:
New polyols; oligomers, and polymers made from the polyols; and binders made from the new polyols, oligomers, or polymers that can be used in binders, where the binders typically include one or more polyols, and a polyfunctional acid or a polyfunctional nitrile.

Disclosed are compositions and methods for the production of mono-esters and di-esters from the reaction of HMF and a reactant selected from a diacid or a diacid derivative; typical reactants are PAN, phthaloyl dichloride, dimethyl phthalate, maleic acid, and maleic anhydride or mono-esters that can be prepared from HMF and MAN.

摘要:
A method for the preparation of a polyol fatty acid ester utilizes a combination of methyl soyate and a polyol in a molar ratio of approximately 2:1 in the presence of a basic catalyst to produce a fatty acid ester. Methanol is removed during a distillation process to drive the reaction process. Optionally, gas sparging can be utilized to aide in methanol recovery. In one embodiment, the method is employed to produce a propylene glycol disoyate product that does not require further purification or distillation to remove a relatively high boiling methyl soyate reactant.
摘要:
Difunctional aromatic diamines (e.g. Ethacure® 100 and 300) are derivatized with furan-2,5-dicarboxylic acid (FDCA) to form FDCA-derived bisamides; the derivatives have enhanced curative properties when used as curatives for polyureas, hybrid epoxy-urethanes, hybrid urea-urethanes, chain extenders for polyurethane and polyurea elastomers, and also for reaction injection molding (RIM) products.
摘要:
A method for producing a psychotropic response, especially for alleviating the symptoms of alcohol withdrawal, comprises administering to a human or animal subject in need thereof a psychotropically effective non-toxic amount of an oxyoctadecanoate. A composition for use in the present method is provided.

摘要:
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.
