  • Itaconic acid polymers and copolymers
    Patent number: 11214758
    Abstract: The disclosed technology relates to esterified and/or ether containing polymers derived from itaconic acid that are free of the less reactive tri-substituted vinyl monomers (e.g., citraconic acid or mesaconic acid) that may be used, for example, as builders in detergent applications, such as in the personal and home care market.
    Type: Grant
    Filed: March 13, 2015
    Date of Patent: January 4, 2022
    Assignee: Lubrizol Advanced Materials, Inc.
