Abstract: The present invention provides novel polymers having chelating functionality and comprising units derived from an ethylenically unsaturated aminocarboxylate monmomer which comprises units derived from ethylenediamino disuccinic acid or its salt and a polymerizable ethylenically unsaturated monomer. The polymerizable ethylenically unsaturated monomer may be selected from divinylbenzene monoepoxide, allylglicidyl ether, and glycidyl(meth)acrylate. The polymer may also comprise units derived from one or more ethylenically unsaturated monomers.

Abstract: The present invention is a process for converting a phosphonate to a hydroxyalkyl phosphonic acid comprising the step of contacting together water, the phosphonate, and a sulfonated or phosphonated heterogeneous catalyst under conditions sufficient to convert at least 50% of the phosphonate to the hydroxyalkyl phosphonic acid. The process of the present invention provides a way of preparing hydroxyalkyl phosphonic acids safely and economically, without corrosive effects.
