  • Publication number: 20200190420
    Abstract: Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions that can be used when the non-polar composition is in a flow, and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone with a longest span having a molecular weight that remains substantially unchanged under the flow conditions and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

  • Patent number: 10400186
    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.
