Synthesis of Branched Polymers by Cationic Polymerization Bernadette Charleux 1 , Rudolf Faust 2 1 Laboratoire de chimie macromoléculaire, Université Pierre et Marie Curie, T44, E1, 4, Place Jussieu F-75252 Paris cedex 05, France E-mail: charleux@ccr.jussieu.fr 2 University of Massachusetts, Lowell Chemistry Department, 1 University Ave. Lowell, MA 01854, USA E-mail: Rudolf_Faust@uml.edu The synthesis of branched polymers by cationic polymerization of vinyl monomers is reviewed. This includes star, graft, and hyperbranched (co)polymers. The description is essentially focused on the synthetic approach and characterization results are provided as a proof of the structure. When available, specific properties of the materials are also given. Keywords.
