MATIERES SILICEUSES A LA SURFACE DESQUELLES EST FIXE UN PRODUITENZYME-POLYMERE

摘要

Enzyme-polymer products are covalently bound to siliceous materials by siliation of the siliceous material to provide functional groups which react with functional groups in the polymer-enzyme molecule. Alternatively, the polymer is first reacted with the reactive groups of the organosilated siliceous material and the enzyme subsequently reacted with the product of this reaction. The product in either case is an insoluble enzymatically-active siliceous material in which the enzyme is covalently bound to the polymer molecule which is in turn covalently bound to the surface of the organosilated siliceous material.
