“…[395][396][397] On the other hand, polymeric azo compounds were also prepared by the termination of living poly(VE) with an azo-containing alcohol. 398 With the advent of living/controlled radical polymerization, the synthesis of well-defined block copolymers having various monomer units that do not undergo cationic polymerization has been expanded, as shown in Figures 25 and 26. PSt with chlorine termini, obtained by living cationic polymerization with R-Cl/Lewis acid, was subsequently used for the ATRP of acrylates and methacrylates, without any additional reactions (68).…”
