Abstract
AbstractActivators regenerated by electron transfer (ARGET) for atom transfer radical polymerization (ATRP) of acrylonitrile (AN) was investigated using carbon tetrachloride (CCl4) as initiator, ferric trichloride anhydracs (FeCl3)/iminodiacetic acid (IDA) as catalyst system, L‐ascorbic acid (VC) as reducing agent, and N,N‐dimethylformamide (DMF) as solvent. Kinetic data of polymerization demonstrated the features of living/controlled free‐radical polymerization. The conversion of AN increased with the increasing concentration of CCl4, [FeCl3]/[IDA] catalyst system and VC. The molecular weight decreased with the increasing concentration of CCl4, [FeCl3]/[IDA] catalyst system and VC. The value of polydispersity index (PDI) increased with the increasing concentration of [FeCl3]/[IDA] catalyst system and VC, while the value of PDI decreased first and then increased with the increasing concentration of CCl4 and IDA. 1H‐NMR spectra of PAN further verified the features of living/controlled free radical polymerization of AN. © 2010 Wiley Periodicals, Inc.
