METHOD OF PRODUCING POLYACRYLAMIDE HYDROGEL Russian patent published in 2013 - IPC C08F2/10 C08F120/56 C08F20/56

Abstract RU 2499003 C1

FIELD: chemistry.

SUBSTANCE: method is realised by polymerising an aqueous solution containing 7-15 wt % acrylamide and 0.5-1.5 wt % N,N'-methylene bisacrylamide under the action of a redox system: ammonium persulphate and N;N,N',N'-tetramethyl ethylenediamine, wherein polymerisation is carried out in the presence of 0.01-0.12 wt % mercaptoacetic acid.

EFFECT: high structural homogeneity of the hydrogel.
