ABSTRACT:
Sulfo-organophosphonic acid compounds react by a metathesis reaction in a liquid medium with tetravalent metal ions, yielding layered crystalline to amorphous inorganic polymers having the empirical formula M(O.sub.3 PRSO.sub.3 H).sub.2 where M is a tetravalent metal and R is an organic group covalently bonded to phosphorus and the terminal sulfonic acid group. One use for the compounds is as ion exchangers.
