Annemarie C. Reimschuessel 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).

  • Process for improving the properties of polymers
    Patent number: 5496918
    Abstract: This invention relates to a process of forming a polyamide composition having increased crystallization rate which comprises the steps of reducing the oligomeric polyamide content of said composition to less than 8% by weight of the composition, preferably with prior melt shearing, use of 1-2% nucleating filler e.g. talc and a mold release agent.
    Type: Grant
    Filed: October 13, 1994
    Date of Patent: March 5, 1996
    Assignee: AlliedSignal Inc.
    Inventors: Yash P. Khanna, Kevin R. Slusarz, Mina K. Gabriel, Annemarie C. Reimschuessel, John P. Sibilia
  • Process for improving the properties of polymers
    Patent number: 5324816
    Abstract: This invention relates to a process for improving the optical, thermal and/or mechanical properties of a polymer by subjecting a melt of the polymer to a shearing action at an effective shear rate, as for example a shear rate of greater than about 100 sec.sup.-1, for a time sufficient to improve said properties.
    Type: Grant
    Filed: June 14, 1989
    Date of Patent: June 28, 1994
    Assignee: Allied-Signal Inc.
    Inventors: Yash P. Khanna, John J. Belles, Jr., Annemarie C. Reimschuessel, Asis Banerjie
  • Process for improving the properties of polytetrafluoroethylene
    Patent number: 5122592
    Abstract: This invention relates to a process of preparing polytetrafluoroethylene comprising one or more fractions of polyethylene having a melting point of greater than about 340.degree. C. by subjecting a polytetrafluoroethylene to a shear at elevated temperature.
    Type: Grant
    Filed: September 1, 1989
    Date of Patent: June 16, 1992
    Assignee: Allied-Signal Inc.
    Inventors: Yash P. Khanna, Georgette Chomyn, Rakesh Kumar, Annemarie C. Reimschuessel
  • Process for improving the properties of polymers
    Patent number: 5091508
    Abstract: This invention relates to a process of modifying the crystallization temperature (T.sub.cc) of polymers, such as polyesters or polyamides, the polymers produced by this process and the molding compositions containing these polymers. The process comprises cooling a polymer to a temperature sufficient to allow grinding of the polymer to an effective particle and then grinding said polymer to the effective particle size in order that the polymer exhibits an increased T.sub.cc.
    Type: Grant
    Filed: May 8, 1991
    Date of Patent: February 25, 1992
    Inventors: Yash P. Khanna, Annemarie C. Reimschuessel
  • Nucleating system for polyamides
    Patent number: 4749736
    Abstract: This invention relates to a crystalline polyamide corporation having dispersed therein a nucleating agent composed of one or more finely divided inorganic materials, one or more fatty acid amides and one or more low molecular weight polymers selected from the group consisting of polyolefins, polyoxides and polsulfides.
    Type: Grant
