摘要

Acrylamide polymerization initiated with a redox initiation system consisting of cericion and ethyl N

N-diethyldithiocarbamyl acetate (EDCA) has been studied. It was foundthat the polymerization rate equation is in good agrement with that of a redox initiatedpolymerization

and the overall activation energy of the polymerization was determinedto be 25.2kJ·mol-1. Accordingly

the system belongs to a redox initiator. The initiationmechanism was proposed based on the end group analysis using FT-IR

UV spectroscopies.Analysis results revealed that the N

N-diethyldithiocarbamyl radical produced from the redox reaction of EDCA with ceric ion can initiate acrylonitrile (AN) polymerization and form the end group on PAN.The resulting PAN was photopolymerized with butyl acrylate (BA) to form PAN-b-PBA block copolymer.
