  • Bio-renewable plasticizers derived from vegetable oil
    Patent number: 9315650
    Abstract: A composition includes estolide esters of vegetable oil fatty acid alkyl esters where the vegetable oil has an unsaturation greater than 90 IV. The fatty acid alkyl esters include unsaturated and saturated fatty acid alkyl esters, and each unsaturated fatty acid alkyl ester has greater than one estolide ester functionality.
    Type: Grant
    Filed: February 20, 2013
    Date of Patent: April 19, 2016
    Assignee: Regents of the University of Minnesota
    Inventors: Dharma R. Kodali, Lucas J. Stolp, Mrinal Bhattacharya

  • Biodegradable compositions produced by reactive blending of synthetic and naturally occurring polymers
    Patent number: 5446078
    Abstract: A biodegradable interpolymer and composition is prepared by the reactive blending of a synthetic polymer having functional groups with a naturally occurring biodegradable polymer such as a carbohydrate or protein compound. During reactive blending, the synthetic polymer can undergo a chemical reaction with the biodegradable natural polymer which results in covalent and physical bonding between the two polymers, thereby forming an interpolymer. By this process, a biodegradable interpolymer composition is produced that is suitable for molding various articles.
    Type: Grant
    Filed: March 8, 1994
    Date of Patent: August 29, 1995
    Assignee: Regents of the University of Minnesota
    Inventors: Utpal R. Vaidya, Mrinal Bhattacharya
