The reaction of living polystyrene with chloro-ended polystrene was studied to examine "the kinetic excluded volume effect" on the intermolecular reaction between reactive chain-ends of two monodisperse polymers. The reaction of living polystyrene with 1-chloropentane was also studied as a model rea

## Abstract **Summary:** We report the synthesis of well‐defined block copolymers by covalent coupling of hydroxy end‐functionalized polymers. Using the high volatility of the coupling agent phosgene as compared to the solvent, very high conversion (up to 96%) is obtained in a one‐pot reaction with
