二羟基二过碘酸合镍(Ⅳ)氧化还原引发丙烯酰胺聚合反应动力学的研究

摘要

The kinetics of acrylamide (AAM) polymerization initiated by diperiodatonickelate(Ⅳ) periodate complex was studied in aqueous alkaline medium.The results indicate that the equation of the polymerization rate is as follows:R p=k[Ni(Ⅳ)] 0 72 [AM] 1 41 and the overall activation energy of AAM polymerization is 41 33kJ/mol.The polymer molecular weight decreases with increasing [Ni(Ⅳ)] and increases with increasing [AAM].The effects of various reaction conditions on the polymerization rate were also studied.The initiation mechanism was proposed.
