  • Process for treating blood with polyimide carriers
    Patent number: 5356374
    Abstract: The present invention relates to a process for treating blood. The process involves separating the blood into plasma and cellular components. The plasma component is passed through a column containing a polyimide particulate carrier. The polyimide carrier contains immobilized proteins, such as protein A, bonded to its surface. The polyimide carrier can be used for removing or modifying a biochemically active substance in the blood plasma.

  • Reactive fluid adhesive compositions
    Patent number: 4226954
    Abstract: Reduced odor is achieved in certain reactive fluid adhesive compositions while maintaining adequate adhesive properties by using higher molecular weight (C.sub.10 -C.sub.18) acrylic and methacrylic ester monomers in combination with minor quantities of diacrylate or dimethacrylate monomers, instead of lower molecular weight acrylic and methacrylic ester monomers generally used in such adhesives.
