A new technique,rheometer equipped with a four-blade vane test fixture was used to investigate the idle time of cross-linking polymerization of acrylamide.The cross-linking polymerization of acrylamide and N,N’-menthylene-bis-acrylamide was initiated by ammonium persulfate and N,N,N’,N’,-tetramethylethylenediamine redox initiator system..The basic aspects effect of initiators and monomer on the experimental temperature and idle time of polymerization were studied by vane method.The effect of pH value on the...
