<p>Matrix comprising molecules of a nitrile-containing polymer which provides solely on the surface of the matrix sufficient uncharged substituted amide groups to render the surface hydrophilic. The invention also provides an article of manufacture comprising the matrix. Another aspect of the invention provides a method of producing a matrix having a hydrophilic surface which comprises treating molecules of a nitrile-containing polymer so as to derivatize a portion of the nitrile groups of the polymer and provide solely on the surface of the matrix sufficient uncharged, hydrophilic substituted amide groups to render the surface hydrophilic. Another embodiment of the invention concerns improved methods of filtration, ultrafiltration, microfiltration, reverse osmosis, dialysis, pervaporation, sieving, affinity chromatography, affinity purification, affinity separation, or affinity adsorption which comprises using the article of manufacture.</p> |
