ABSTRACT:
Solid inorganic polymers are derivatives of phosphorous or phosphonic acids which contain cyclic organo groups selected from the group consisting of alicyclics, aromatics and heterocyclics. They are characterized by the structural linkage of three oxygens bonded to phosphorus to one or more tetravalent metals selected from the group consisting of titanium, zirconium, cerium, hafnium, lead, thorium and uranium. The molar ratio of phosphorus to tetravalent metal is about 2 to 1. One use for the polymers is as stationary phases or supports in chromatography.
