## Abstract **Summary:** Segmented block copolymers were synthesized in melt by conversion of carboxy‐terminated poly(propylene oxide) and amino‐terminated PA12 with a selectively reacting bifunctional coupling agent bearing one oxazoline and one oxazinone group. The reaction was performed either i

## Abstract A new route of synthesis of block copolymers was investigated. It involves the polymerization of a side‐chain liquid‐crystalline acrylate and poly(propylene glycol), modified by an esterification reaction with mercaptoacetic acid used as macrotransfer agent, in the presence of 2,2′‐azoi
