Abstract

Wynalazek dotyczy poliamfolitu o wzorze ogólnym 1, pochodnego kwasu dimetylofosfinowego i kwasu 2-aminoetanosulfonowego. Przedmiotem wynalazku jest równiez sposób wytwarzania poliamfolitu pochodnego kwasu dimetylofosfinowego i kwasu 2-aminoetanosulfonowego, który polega na tym, ze w pierwszym etapie jedna czesc molowa kwasu fosfinowego poddaje sie reakcji z jedna czescia molowa kwasu 2-aminoetanosulfonowego i co najmniej jedna czescia molowa formaldehydu. Reakcje prowadzi sie w temperaturze 293-373 K, w wodzie, w obecnosci aktywatora w postaci kwasu solnego, az do przereagowania substratów i utworzenia sie mieszaniny fosfinometylowanych pochodnych kwasu 2-aminoetanosulfonowego, która w drugim etapie poddaje sie reakcji polikondensacji z co najmniej jedna czescia molowa formaldehydu. Reakcje prowadzi sie w temperaturze 293-373 K, w wodzie, w obecnosci aktywatora w postaci kwasu, az do zakonczenia polikondensacji.The invention relates to a polyampholite of general formula 1, a derivative of dimethylphosphinic acid and 2-aminoethanesulfonic acid. The invention also relates to a process for producing polyphosphite derivative of dimethylphosphinic acid and 2-aminoethanesulfonic acid, which consists in the first stage that one molar part of phosphinic acid is reacted with one molar part of 2-aminoethanesulfonic acid and at least one molar part of formaldehyde. Reactions are carried out at a temperature of 293-373 K, in water, in the presence of an activator in the form of hydrochloric acid, until the reactants react and the formation of a mixture of phosphinomethylated derivatives of 2-aminoethanesulfonic acid, which in the second stage undergoes a polycondensation reaction with at least one molar part formaldehyde. Reactions are carried out at a temperature of 293-373 K, in water, in the presence of an activator in the form of acid, until the end of polycondensation.
