Patents by Inventor Moris S. Eisen

Moris S. Eisen 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).

  • Patent number: 8944257
    Abstract: The invention provides modified polysulfones substituted in one or more of the phenyl rings by functional groups and membranes composed of the modified polysulfones. Also provided are methods for the preparation of monodispersed nanoporous polymeric membranes. The membranes are useful for reverse osmosis, nanofiltration, and ultrafiltration, particularly for purification of water.
    Type: Grant
    Filed: August 20, 2008
    Date of Patent: February 3, 2015
    Assignee: Technion Research and Development Foundation Ltd.
    Inventors: Moris S. Eisen, Raphael Semiat, Natalia Vainrot
  • Patent number: 8672145
    Abstract: A sorbent polymer is provided that interacts or reacts with aqueous urea to aid the regeneration of a dialysate liquid. The sorbent polymer may include one or more specific functional groups bonded thereto. Such specific functional groups are selected from carboxylic acids, carboxylic acid esters, carboxylates, amides, dicarboxylic acids, dicarboxylic acid esters, and dicer boxylates to produce the desired urea sorbent.
    Type: Grant

  • Patent number: 5455317
    Abstract: The synthesis, and use as precatalysts of chiral organozirconium complexes for olefin polymerization are disclosed, having the structure (C.sub.5 R'.sub.4-x R*.sub.x) A (C.sub.5 R".sub.4-y R"'.sub.y) M Q.sub.p, where x and y represent the number of unsubstituted locations on the cyclopentadienyl ring; R', R", R"', and R* represent substituted and unsubstituted alkyl groups having 1-30 carbon atoms and R* is a chiral ligand; A is a fragment containing a Group 13, 14, 15, or 16 element of the Periodic Table; M is a Group 3, 4, or 5 metal of the Periodic Table; and Q is a hydrocarbyl radical, or halogen radical, with 3.ltoreq.p.ltoreq.o. Related complexes may be prepared by alkylation of the corresponding dichorides. In the presence of methylalumoxane or triarylborane cocatalysts, these complexes form "cation-like" species which are highly active for olefin polymerization. In combination with a Lewis acid cocatalyst, propylene or other .alpha.
