  • Layered or amorphous cyclic organometallic inorganic polymers
    Patent number: 4373079
    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.

  • Layered zirconium bis(benzenephosphonate) inorganic polymers
    Patent number: 4267308
    Abstract: Phenylphosphonic acid reacts by a metathesis reaction in a liquid medium with tetravalent zirconium ions, yielding layered crystalline to amorphous inorganic polymers having the empirical formula Zr(O.sub.3 PC.sub.6 H.sub.5).sub.2. One use for the compound is as a sorbent for small quantities of organic materials in aqueous solutions.
