ORGANOPHOSPHONIC POLYMERS AND THEIR USE AS STABILIZERS FOR AQUEOUS SOLUTIONS OF HYDROGEN PEROXYDE |
摘要 |
Organophosphonic polymers of general formula (I) where Y is a methyl or ethyl group or hydrogen and Z is hydrogen, the ammonium group, an alcaline metal or an alcaline earth metal. A method for producing these polymers comprises three stages: production of a monomer by reacting a ketene with diethylphosphite in the presence of an acid catalyst; polymerization of the monomer in solution in a solvent by means of a free radical initiator; hydrolysis of the polymer obtained by means of a concentrated solution of inorganic or inorganic based acid. Aqueous solution of hydrogen peroxyde stabilized by means of said polymers. |
