FIELD: production of hydrolysed polyacrylamide.
SUBSTANCE: invention relates to the production of hydrolysed polyacrylamide in an aqueous solution. A method has been proposed for producing hydrolysed polyacrylamide by sequentially dissolving polyacrylamide 0.007-0.71 wt.%, crystalline hydrate of copper sulphate 0.025-2.495 wt.% and sodium tetrahydride borate 0.008-0.756 wt.% in distilled water with constant stirring followed by keeping at 25°C for 1-24 hours, after which the solution of hydrolysed polyacrylamide is separated by decantation.
EFFECT: production of hydrolysed polyacryamide and the simplification of the method for its production, with the possibility of achieving different degrees of hydrolysis.
