  • Modification of segmented polyurethane properties by copolymerizing with pendant functionalized diols
    Patent number: 11116211
    Abstract: A functionalized polyurethane polymer is provided, the polymer defined by the formula where each R? is independently derived from a diisocyanate, where each R? represents the soft segment of the polymer, where n is the number of repeat units within the soft segment of the polymer, where m is the number of repeating mer units in the polymer, where each E is a pendant-functionalized amide unit chain extender, wherein the nitrogen atom of the amide group is part of the polymer backbone. A method for preparing the polymer is also provided.
    Type: Grant
    Filed: June 12, 2019
    Date of Patent: September 14, 2021
    Assignee: The University of Akron
