This disclosure provides methods for the chemical modification of triglycerides that are highly enriched in specific fatty acids and subsequent use thereof for producing functionally versatile polymers.

Hydroformylated triglycerides and uses thereof

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/ftto about 5.0 lbs/ftas measured by ASTM D1622. Further disclosed are the foam and a method for installing the foam.

Foam, composition, and method

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.

Production of polyols using distillers grains and proteins and lignin extracted from distillers grains

A method of making a biobased-petrochemical hybrid polyol is provided. This method includes reacting a cyclic ether with a vegetable oil-based polyol in the presence of a cationic catalyst or a coordinative catalyst that includes a vegetable oil-based polyol ligand to form the biobased-petrochemical hybrid polyol. The biobased-petrochemical hybrid polyol that is created has a number average molecular weight of about 3,000 to about 6,000 and has a structure that is about 22% to about 36% biobased. In one aspect of the present invention, the cyclic ether is propylene oxide, and the propoxylated polyol formed from the propylene oxide and vegetable oil-based polyol is then reacted with ethylene oxide in the presence of a superacid catalyst to create a block copolymer with a terminal polyethylene oxide block having a high percentage of terminal primary hydroxyl groups. If the cyclic ether is a homogeneous mixture of ethylene oxide and propylene oxide, then propylene oxide-ethylene oxide random copolymers are formed by polyaddition to vegetable oil polyols. The biobased-petrochemical hybrid polyol may be reacted with an isocyanate so as to create a flexible polyurethane that has good hydrolytic resistance.

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).

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&#xb0; 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).
