| abstract | 1456974 Ion exchange materials NATIONAL RESEARCH DEVELOPMENT CORP 11 Dec 1973 [10 Jan 1973] 1277/73 Heading C3P Particulate ion exchange materials are produced by heating particles of an inorganic material at 100‹ to 550‹ C. to produce a porous inert inorganic substrate, adsorbing an organic monomer into the substrate and polymerizing the adsorbed monomer so that the resultant polymer is retained within the pores of the substrate and, if necessary, intoducing ion exchange groups into the polymer. The inorganic material may be an inorganic oxide gel or a silicate. The monomer may be acrylic acid, an acrylic ester, styrene, sulphonated styrene, vinyl pyridine, acrylamide or a vinylamine and may be polymerized in the presence of a cross-linking agent, e.g. divinyl benzene. The substrate may be soaked in the monomer or the monomer may be adsorbed on to the substrate from the vapour phase. The polymerization may be initiated using a free radical initiator, ultraviolet light or gamma or X-ray radiation. In the examples stannic chloride or silica gel is heated and then immersed in a mixture of acrylic acid or vinylpyridine and azobisisobutyronitrile with the monomers being polymerized in the pores of the substrate. |
