  • High temperature underfilling material with low exotherm during use
    Patent number: 6548575
    Abstract: A curable underfill composition comprising an epoxy containing a curing agent component and a latent accelerator component. The accelerator component comprises a material which produces a resin with an exotherm below 300 J/g. Further, the combination may be utilized in an unfilled state which allows the epoxy to remain very viscous and thus increases the speed of the underfill process in comparison to filled epoxy compositions and epoxy compositions containing different accelerator components.
    Type: Grant
    Filed: December 13, 2000
    Date of Patent: April 15, 2003
    Assignee: National Starch and Chemical Investment Holding Corporation
    Inventors: Neil M. Carpenter, Michel Ruyters

  • Derivatives of 1,4-dideoxy-1,4-imino-D-mannitol and preparation thereof
    Patent number: 5041555
    Abstract: Novel derivatives of 1,4-dideoxy-1,4-imino-D-mannitol and method for their synthesis from 4,5-anhydro-1-azido-1-deoxy-2,3-O-isopropylidene-D-talitol or its triflate derivative are disclosed. The novel derivatives, 6-fluoro-1,4-imino-1,4,6-trideoxy-D-mannitol and the N-butyl and N-benzyl derivatives of 1,4-dideoxy-1,4-imino-D-mannitol, have useful mannosidase inhibitory activity.
    Type: Grant
    Filed: September 21, 1990
    Date of Patent: August 20, 1991
    Assignee: Monsanto Company
    Inventors: George W. J. Fleet, Bryan Winchester, Neil M. Carpenter
  • Derivatives of 1,4-dideoxy-1,4-imino-D-mannitol and a process for their preparation
    Patent number: 4996329
    Abstract: Novel derivatives of 1,4-dideoxy-1,4-imino-D-mannitol and method for their synthesis from 4,5-anhydro-1-azido-1-deoxy-2,3-O-isopropylidene-D-talitol or its triflate derivative are disclosed. The novel derivatives, 6-fluoro-1,4-imino-1,4,6-trideoxy-D-mannitol and the N-butyl and N-benzyl derivatives of 1,4-dideoxy-1,4-amino-D-mannitol, have useful mannosidase inhibitory activity.
