Christian Dollendorf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Ultra violet assisted photo initiated free radical polymerization
    Patent number: 11041037
    Abstract: A method of producing a polymerized product through an inverse emulsion polymerization reaction. The current method includes introducing an ultraviolet (UV) light sensitive initiator into an inverse emulsion monomer formulation comprising monomers and irradiating the monomer formulation with an UV light source. A polymerized product is formed from polymerization of the monomers in the presence of the irradiated UV light sensitive initiator.
    Type: Grant
    Filed: October 1, 2018
    Date of Patent: June 22, 2021
    Assignee: SOLENIS TECHNOLOGIES, L.P.
    Inventors: Christian Dollendorf, Markus Broecher, Patric Bierganns
  • Adiabatic gel polymerization process for the production of water-soluble polyelectrolytes
    Patent number: 10647823
    Abstract: The current process relates to an adiabatic gel polymerization process for the production of water-soluble polyelectrolytes using UV LED modules or a combination of a UV tube light sources and UV LED modules wherein the resulting polymer has increased throughput, lower residual monomer content as well as lower insolubles compared with current photoinitiated polymerization processes.
