Rheological monitoring of in situ poly(acrylamide) gel preparation

The sol-gel transition for a polyacrylamide gel during in situ preparation was investigated by dynamic rheology at constant frequency of 0.1 Hz and by means of temperature, pH and conductivity variation. The gels were prepared by polymerization of acrylamide crosslinked with N, N'- methylene-bi...

Summary:The sol-gel transition for a polyacrylamide gel during in situ preparation was investigated by dynamic rheology at constant frequency of 0.1 Hz and by means of temperature, pH and conductivity variation. The gels were prepared by polymerization of acrylamide crosslinked with N, N'- methylene-bis-acrylamide using a redox initiation (potassium persulfate / ascorbic acid) system
