Synthesis of poly (ethylene amine) on an oxide support

Abstract

Methods of polymerizing polyethylene-based polymers on a support, and supports coated with polyethylene-based polymers. The coated supports may be used to improve the ink fixation properties of an ink-jet printing medium. The coated supports may also be useful for highly tailored chromatographic separations.

       7 . A catalyst comprising: 
 a surface comprising a polymer formed from a plurality of monomers comprising one or more monomer types, at least one of the one or more monomer types having an amine functional group; and    an active molecule immobilized on the surface, wherein the active molecule is selected to promote a chemical reaction in a reagent.    
   
   
       8 . The catalyst of claim  0 , wherein the active molecule is an enzyme.  
   
   
       9 . The catalyst of claim  0 , wherein the active molecule is a metal.  
   
   
       10 . The catalyst of claim  0 , wherein one of the one or more monomer types is ethylene imine.  
   
   
       11 . The catalyst of claim  0 , wherein one of the one or more monomer typos is ethylene oxide.  
   
   
       12 . The catalyst of claim  0 , wherein the catalyst acts as a selective catalyst.  
   
   
       13 . The medium of claim  0 , wherein the polymer has a porosity, pore dimension, hydrophobicity pH, or surface chirality selected to promote separation of components of the reagent.
