Synthesis of an azo macromolecular initiator composed of polyamide 4 and its initiation activity for the radical polymerization of vinyl monomers

Polyamide 4 containing an azo group (azo‐PA4) was synthesized by the ring‐opening polymerization of 2‐pyrrolidone when 4,4′‐azobiscyanopentanoyl chloride was used as an initiator. It was possible to control the molecular weight (MW) of the azo‐PA4s through the concentration of the initiator to some...
