  • Bio-based foam from natural oils
    Patent number: 8633257
    Abstract: The invention relates to foam derived from natural oils, e.g. plant and animal oils. The oils are functionalized to allow for the preparation of foams with desired chemical and physical properties, such as density and robustness. The foam may contain a triglyceride having a first set of functional groups, and a second compound or chain extender (e.g., a second triglyceride, a fatty acid or polyethylene glycol) having a second set of functional groups capable of reacting with the first set of functional groups to form a covalent bond.
