Delong Liu, Hou Chen, Naiyi Ji and Zhi Tan Living radical polymerization of acrylonitrile catalyzed by copper with a high concentration of radical initiator and its application in removal of Ag(I) after modification Journal of Polymer Science Part A: Polymer Chemistry 51
The synthesis of PAN via living radical polymerization in DMF using CCl4 as initiator, CuCl2/HMTA as catalyst system, and AIBN as a radical initiator, is reported. The polymerization proceeds in controlled/living manner as indicated by first-order kinetics of the polymerization rate with respect to the monomer concentration, linear increase of the molecular weight with monomer conversion, and narrow polydispersity. The modified PAN containing amidoxime group was used for extraction of Ag(I) ions from aqueous solutions.
