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′‐azoisobutyronitrile as initiator. The molecular weight of the liquid‐crystalline blocks is determined by the molar ratio between the reactants.
