Abstract
Procedeul de hidroliza partiala a poliacrilamidei în sistem omogen, conform inventiai, folosind ca agenti de hidroliza NaHCO3, NaCO3 sau NaOH, consta în aceea ca agentul de plimer cu concentratiea de 10...30% se supune hidrolizei la temperatura de 10...45 degree C, în prezenta unui activator de reactie, ales dintre KCl, NaCl, adaugat în cantitate de 0,5...50% în greutate raportat la polimerul supus reactiei de hidroliza, timpul de hidroliza optim fiind cuprins între 0,25 si 3 h, fiind în functie de agentul e hidroliza care se adauga în stare solida sau sub forma de solutii apoase.
