Abstract

Inventia de fata se refera la un procedeu pentru prepararea unei solutii apoase de poliacrilamida, partial hidrolizata, utilizata la recuperarea petrolului din formatiunile subterane, prin polimerizarea monomerului, în prezenta de catalizator redox, apoi polimerul se hidrolizeaza cu solutie apoasa de hidroxid de metal alcalin, într-o astfel de cantitate ca sa hidrolizeze 20...40% din grupele amidice, iar, în final, polimerul se dilueaza cu apa pîna la o concentratie de 50...5000 ppm.
