Abstract
Layered solid inorganic polymers having at least one organo group anchored to a surface of the polymer, and which can be useful in catalysis, lubrication, ion-exchange, chromatography and absorption processes, can be made by reacting at least one tetravalent metal (e.g., zirconium, cerium, thorium, uranium, lead, hafnium, titanium, etc.) and two or more acids selected from phosphoric acid, phosphonic acid and organophosphorus acids of the formula ((HO).sub.2 OP).sub.n R wherein n is 1 or 2 and R is an organo group covalently bonded to the phosphorus atom. Preferably the reaction is conducted with a stoichiometric excess of phosphorus acids in a liquid medium in which a compound of the metal is soluble. The covalent bonding can be through oxygen to produce phosphates, or through carbon to produce phosphonates.
