Patents by Inventor Thorsten Werner Brockmann

Thorsten Werner Brockmann 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).

  • Protected aminofunctionalized polymerization initiators and methods of making and using same
    Patent number: 6943250
    Abstract: Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality is part of a heterocyclic radical and includes a protecting group.
    Type: Grant
    Filed: March 6, 2001
    Date of Patent: September 13, 2005
    Assignee: FMC Corporation
    Inventor: Thorsten Werner Brockmann
  • Protected aminofunctionalized polymerization initiators and methods of making and using same
    Patent number: 6891019
    Abstract: Anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The amine functionality includes a first protecting group, which can be aralkyl, methyl, allyl or tertiary alkyl group. The other of the amine protecting groups can be the same as the first protecting group. Alternatively, the second protecting group can be different from the first protecting group, in which case it is selected to have differential stability to agents used to remove the aralkyl, methyl, allyl or tertiary alkyl protecting group.
    Type: Grant
