THREE DIMENSIONAL CARRIER OF INORGANIC POROUS MATERIALLREACTIVE POLYMER AND METHOD OF MAKING SAME

摘要

The invention relates to three-dimensional carriers consisting of inorganic porous material and 0.001-95% of unextractably sorbed reactive polymer of the general formula I: I. where R1, R2, R4 respectively are hydrogen atom, alkyl with 1-5 carbon atoms, or aryl, and R3 is the group -COO-(CH2)n-, and to a method for its preparation. The three-dimensional carriers may be prepared by coating the inorganic porous material with a monomer, which is left to polymerize under the conditions of solution polymerization, while the soluble polymer, which is not bound on the surface of the inorganic material, is removed by extraction. The three-dimensional carrier may also be prepared by depositing a solution of a polymer of general formula I and with a degree of polymerization lower than 103 on the inorganic porous material, leaving the two materials in contact with each other, and separating the unbound polymer by extraction. The carriers of inorganic porous material-reactive polymer combine good properties of the inorganic material with the high reactivity of the polymeric coating. An advantage of the carrier is not only the combining of inorganic porous materials with a polymer containing epoxy groups, but also an ample opportunity of modifying the carrier by chemical reactions of the epoxy group. This opportunity may be employed in bonding biologically active compounds, dyes, complex-forming compounds and other low-molecular and high-molecular weight compounds to the carrier.
