Abstract
Organofosfonsyre-polymerer som tilsvarer den følgende generelle formel: hvor Y er en metyl- eller etylgruppe eller et hydro- genatom og Z angir et hydrogenatom, ammoniumgruppen eller et alkalimetall- eller jordalkalimetall-atom, og hvor x er et helt tall lik l dersom Z angir et hydrogenatom, ammoniumgruppen eller et alkalimetall- atom, eller 2 dersom Z angir et jordalkalimetall- atom; samt fremgangsmåte for fremstilling av poly- merene i tre trinn: - fremstilling av en monomer ved reaksjon av et keten med dietylfosfitt i nærvær av en sur ka- talysator; polymerisasjon av monomeren i en løsning i et løsemiddel ved hjelp av en friradikal-initi- ator; hydrolyse av den oppnådde polymer ved hjelp av en konsentrert løsning av uorganisk syre eller av uorganisk base, samt vandig hydrogenperoksyd-løsning stablisert ved hjelp av polymerene.Organophosphonic acid polymers corresponding to the following general formula: wherein Y is a methyl or ethyl group or a hydrogen atom and Z represents a hydrogen atom, the ammonium group or an alkali metal or alkaline earth metal atom and where x is an integer equal to 1 if Z denotes a hydrogen atom, the ammonium group or an alkali metal atom, or 2 if Z denotes an alkaline earth metal atom; and the process for preparing the polymers in three steps: - preparation of a monomer by reaction of a chain with diethylphosphite in the presence of an acidic catalyst; polymerization of the monomer in a solution in a solvent by a free radical initiator; hydrolysis of the obtained polymer by means of a concentrated solution of inorganic acid or of inorganic base, and aqueous hydrogen peroxide solution stabilized by the polymers.
