Stereocontrolled radical polymerizations are elusive, owing to the difficulty of controlling facial addition at a propagating planar, sp2 radical chain end. Now, cobalt–porphyrin initiators are reported that enable the preparation of well-defined, highly isotactic polyacrylamides at low Lewis acid loading.
