In this paper, we presented dynamic conductivity controlled in situ polymerization of poly(acrylamide-co-cellulose ehters) hydrogel. Of which varied groups were changed for cellulose ether, e.g. MC, HPC and HPMC, and the recorded curves indicated an selection of these functional groups for co-polymerization with PAAm. According to dynamic conductivity, it was of interest found that the whole gelation is visible in three stages, and the sol to gel is quite clealrly due to a peak visible between these two stages. Moreover, the gel point was also visible presented in this curve with a valley.
