Synthesis of Macromonomers with Polycondensable Groups

In the last decade, several new reactive groups in polycondensation have been employed as ATRP initiators, e.g., lactones [332,333], as follows  

This macromonomer may be employed in the field of electrical conductive polymers. Methacrylate chains provide better processing properties than the usual (pyrole) polymers. 

The graft copolymers were then obtained either by Suzuki [with Pd(PPh3)4] or Yamamoto (with NiCh) reaction [337]  

In the course of synthesizing new macromonomers, ATRP is one of the most appropriate radical techniques, witnessed by the high number of publications in this area. First, like for other LRP, the macromonomers obtained possess macromolecular chains with very low PDI, which confer specific properties. Second, there are several possibilities for synthesizing macromonomers through the ATRP process. Indeed, macromonomers can be
