Patents by Inventor Kamran B. Ghiassi

Kamran B. Ghiassi 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).

  • Publication number: 20240101724
    Abstract: The present invention relates to articles comprising crosslinked polymer network comprising thioether crosslinks and process of making and using same. Such thiol-ene crosslinking reactions not only make the isocyanate crosslinking reaction unnecessary, but they also improve the article's strength due to chemical crosslinking between the article's resin layers, and reduce or eliminate post curing. Thus resulting in a sufficiently cured article in a much shorter time.
    Type: Application

  • Patent number: 11866560
    Abstract: The present invention relates to a microfluidic flow process for making monomers, monomers made by such processes, and methods of using such monomers. In such process, microfluidic reaction technology is used to synthesize cyanation reaction products orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does require strictly regulated, highly toxic cyanogen chloride. Thus the aforementioned process is more economically efficient and reduces the environmental impact of thermosetting resin monomer production, and produces thermosetting resin monomers in greater purity than obtained through typical processes.

  • Patent number: 11738322
    Abstract: The present invention relates to a microfluidic flow process for making polymers, polymers made by such processes, and methods of using such polymers. In such process, a novel reagent delivery setup is used in conjunction with microfluidic reaction technology to synthesize anionic polymerization reaction products from superheated monomer orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does not require the cryogenic temperatures which are required for such syntheses in batch or bulk continuous. Thus the aforementioned process is more economically efficient and reduces the environmental impact of linear polymer production.

  • Patent number: 11518828
    Abstract: The present invention relates to processes for making macromolecular networks, macromolecular networks made by such processes, and methods of using such macromolecular networks. Such process employs a low amount of amine compound as a reaction accelerant. The rates of chemical reaction are thereby easily controlled over several orders of magnitude, permitting efficient catalysis and control of reaction conditions needed to produce thermochemically stable macromolecular networks.
