Study on Polymerization of Acrylonitrile Initiated by Diperiodatoargenate(Ⅲ)Complex Redox System

本文研究了在碱性介质中，二过碘酸合银（Ⅲ）络离子引发丙烯腈自由基聚合反应，测得了各种条件对聚合反应速率的影响，给出了聚合反应速率和表观活化能，探讨了引发反应机理。

The polymerization of acrylonitnie(AN)initiated by diperiodatoargenate(Ⅲ)complex(DPA) redox system in aqueous alkaline medium was studied.The resultsindicate that the rate equation of the polymerization is Rp=K[AN]￣(1.86)[DPA]￣(0.61) and theoverall activation energy of AN polymerization is 48.5kJ/mol.The effects of reaction con-ditions on the polymerization rate were studied,a initiation mechanism was proposed.
