This article describes the construction of branched. ROMP-polymer architectures via polycondensation of AB(n)-type macromonomers. For this convergent strategy, a polymer was synthesized that carries several hydroxyl-groups along the polymer chain and one carboxylic acid group at the chain end. An esterification reaction between these functional groups yielded long-chain branched polymers. The polymers were analyzed by NMR and SEC to monitor the condensation reaction.
