  • Associative polymers for mist-control
    Patent number: 12116540
    Abstract: Polymeric mist control materials, methods of forming polymeric mist control materials, and methods of using such materials for mist control are provided. The polymeric mist control additives are formed of molecules comprised predominantly of monomers that confer high solubility in fuel and include associative groups that attract each other in donor-acceptor manner, and are incorporated such that multiple associative groups are in close proximity (“clusters”), such that the clusters are separated by very long non-associative sequences.
    Type: Grant
    Filed: March 7, 2022
    Date of Patent: October 15, 2024
    Assignee: California Institute of Technology
    Inventors: Ming-Hsin Wei, Julia A. Kornfield, Ralph Leonard Ameri David
