  • Rigid-rod polymers
    Patent number: 5565543
    Abstract: High-performance polymers having a rigid-rod backbone comprising a chain length of at least 25 organic monomer units joined together by covalent bonds wherein at least about 95% of the bonds are substantially parallel; and solubilizing organic groups attached to at least 1% of the monomer units. The polymers are prepared in a solvent system which is a solvent for both the monomer starting materials and the rigid-rod polymer product.
    Type: Grant
    Filed: August 11, 1994
    Date of Patent: October 15, 1996
    Assignee: Maxdem Incorporated
    Inventors: Matthew L. Marrocco, III, Robert R. Gagne, Mark S. Trimmer
  • Macromonomers having reactive side groups
    Patent number: 5512630
    Abstract: Rigid-rod macromonomers, and methods for preparing such macromonomers, having a polyaromatic backbone, solubilizing side groups, and reactive side groups are provided. The macromonomers are chemically incorporated into polymer systems to provide stronger, stiffened polymers.
    Type: Grant

  • Method and apparatus for separating oxygen from a gaseous mixture
    Patent number: 4475994
    Abstract: A process and apparatus is provided for separating oxygen from a mixture of gases such as air. The apparatus includes an electrochemical cell that includes a cathode, an anode and an electrolyte. Oxygen in the air is reduced to the superoxide ion (O.sub.2.sup.-) at the cathode; the superoxide ion is transported across the cell through the electrolyte; and the superoxide ion is then reoxidized to oxygen at the anode and collected.
