Abstract
Inorganic polymeric compounds which contain pendant organic functional groups are prepared by the reaction of an acid of the formula [(HO).sub.2 OZO.sub.x ].sub.k R, in which Z is a pentavalent atom, x is 0 or 1, k is 1 or 2, and R is a cyclic organo group, with a tetravalent metal ion. The polymeric compounds are insoluble in the reaction medium, exist in a layered crystalline to amorphous form, and have the formula M(O.sub.3 ZO.sub.x R).sub.n, in which M is the tetravalent metal and n is 1 or 2. One use for the polymeric compounds is as selective sorbents.
