Acrylonitrile (AN) was polymerized by initiators for continuous activator regeneration (ICAR) atom transfer radical polymerization (ATRP). The effect of the ligand, tris(2-pyridylmethyl)amine (TPMA) and N,N,N’,N’-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN), in the Cu-based catalyst, the amount of catalyst, several alkyl halide initiators, targeted d.p., and amount of azobisisobutyronitrile (AIBN) added were studied. The best conditions utilized 50 ppm of CuBr2/TPMA as the catalyst and 2-bromopropionitrile (BPN) as the initiator. This combination resulted in 46% conversion in 10 h and polyacrylonitrile (PAN) with the narrowest mol. weight distribution (Mw/Mn = 1.11-1.21). Excellent control was maintained after lowering the catalyst loading to 10 ppm, with 56% conversion in 10 h, exptl. mol. weight closely matching the theor. value, and low dispersity (Mw/Mn < 1.30). Catalyst loadings as low as 1 ppm still provided well-controlled polymerizations of AN by ICAR ATRP, with 65% conversion in 10 h and PAN with relatively low dispersity (Mw/Mn = 1.41). High chain end functionality (CEF) was confirmed via 1H NMR anal., for short PAN chains, and via clean chain extensions with Bu acrylate (BA). © 2016 Wiley Periodicals, Inc. J. Polym.
