Patents by Inventor Conrad William Kamienski

Conrad William Kamienski 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: 6362284
    Abstract: Protected, functionalized heterotelechelic polymers, hydrogenated and/or deprotected analogues thereof, and processes to prepare these polymers. Monomers are polymerized using a protected functionalized initiator to form a living polymer, and the living polymer is reacted with an electrophile to form heterotelechelic polymers.
    Type: Grant
    Filed: November 19, 1998
    Date of Patent: March 26, 2002
    Assignee: FMC Corporation
    Inventors: James Anthony Schwindeman, Roderic Paul Quirk, Conrad William Kamienski
  • Patent number: 6197891
    Abstract: A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure: M—Qn—Z—O—[A(R1R2R3)] wherein M is an alkali metal selected from the group consisting of lithium, sodium and potassium; Q is a saturated or unsaturated hydrocarbyl group derived by incorporation of a compound selected from the group consisting of conjugated diene hydrocarbons, alkenylsubstituted aromatic hydrocarbons, and mixtures thereof into the M—Z linkage; Z is a branched or straight chain hydrocarbon group which contains 3-25 carbon atoms, optionally containing aryl or substituted aryl groups; A is an element selected from carbon and silicon; R1, R2, and R3 are independently selected from hydrogen, alkyl, substituted alkyl groups containing lower alkyl, lower alkylthio, and lower dialkylamino groups, aryl or substituted aryl groups containing lower alkyl, lower alkylthio, and lower dialkylamino groups, and n is an integer from 1 to 5, monof

    Filed: November 19, 1998
    Date of Patent: August 22, 2000
    Assignee: FMC Corporation
    Inventors: James Anthony Schwindeman, Roderic Paul Quirk, Conrad William Kamienski, deceased
  • Patent number: 5965681
    Abstract: Protected, functionalized telechelic polymers, hydrogenated and/or deprotected analogues thereof, and processes to prepare these polymers are disclosed. In the invention, a lithium initiator is added to a compound having at least two independently polymerizable vinyl groups to form a dilithium initiator. Monomer is then added to grow or polymerize polymer arms having living ends and the living ends functionalized.

  • Patent number: 5821307
    Abstract: A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure:M--Q.sub.n --Z--OA(R.sup.1 R.sup.2 R.sup.3)wherein M is defined as an alkali metal, selected from the group consisting of lithium, sodium and potassium, Q is an aromatic substituted saturated hydrocarbyl group produced by the incorporation of one or more alkenyl substituted aromatic hydrocarbons containing 8-25 carbon atoms into the M--Z linkage; Z is a branched or straight chain hydrocarbon group which contains 3-25 carbon atoms, optionally containing aryl or substituted aryl groups; A is an element selected from carbon and silicon; R.sup.1, R.sup.2, and R.sup.
