20080281071 | Cationic polymerization of biological oils - A method for the cationic polymerization of unsaturated biological oils (e.g., vegetable oils and animal oils) based on the cationic reaction of double bonds initiated by superacids is provided. The process occurs under very mild reaction conditions (about 70-110° C. and atmospheric pressure) and with short reaction times. The polymerized oils have a viscosity about 10 to 200 times higher than the initial oil and relatively high unsaturation (only about 10-30% lower than that of initial oils). | 11-13-2008 |
20090082483 | POLYGLYCEROL BASED POLYOLS AND POLYURETHANES AND METHODS FOR PRODUCING POLYOLS AND POLYURETHANES - A new class of polyols derived from renewable resources, including polyglycerol and vegetable oils, the use of such polyols in polyurethane foams and cast resins, and methods for making the polyols and polyurethanes are provided. | 03-26-2009 |
20090309064 | CATIONIC POLYMERIZATION OF BIOLOGICAL OILS - A polymerization reaction mixture for the cationic polymerization of unsaturated biological oils (e.g. vegetable oils and animals oils) based on the cationic reaction of double bonds initiated by superacids is provided. The polymerized oils have a viscosity about 10 to 200 times higher than the initial oil and relatively high unsaturation (only about 10-30% lower than that of initial oils). | 12-17-2009 |
20130202793 | FOAM, COMPOSITION, AND METHOD - A method of producing a foam is disclosed. The method includes providing an epoxy-containing compound, a cationic catalyst, an optional blowing agent, and at least one additive. The method further includes combining the epoxy-containing compound with the cationic catalyst, the optional blowing agent, and the at least one additive, wherein the epoxy-containing compound and the cationic catalyst react to polymerize the epoxy-containing compound to provide the foam having a density from about 0.3 lbs/ft | 08-08-2013 |
20140200324 | PRODUCTION OF POLYOLS USING DISTILLERS GRAINS AND PROTEINS AND LIGNIN EXTRACTED FROM DISTILLERS GRAINS - Processes for the production of polyols from sources such as dried distillers grains plus solubles (DDGS) make use of a two-stage reaction scheme. In the first stage, the proteinaceous starting material is reacted with an aminating agent, such as diethanolamine (DEOA), to generate amino-amides and amides. These products are then reacted with an alkoxylating agent, preferably a substituted or unsubstituted epoxide to yield polyols. These polyols may be further reacted with isocyanates to give low-cost rigid polyurethane foams. In alternate forms, lignin may be directly converted to polyols by reaction with an alkoxylating agent, optionally followed by reaction with an isocyanate to produce polyurethanes. | 07-17-2014 |
