A methodology that allows controlling both the functionality and topology of polymers prepared by radical polymerization using a single molecule will be presented. The methodology will be illustrated with on a monomer carrying a xanthate moiety that can be used to introduce branching points and/or pending functional groups. The rational design of the xanthate monomer, as well as the synthesis and characterization of functional linear, branched, grafted and bottlebrush copolymers will be discussed. Parameters and conditions allowing to control the degree of branching and functionality will be evaluated. The synthesis of branched polymers carrying pending polymerizable units as well as amphiphilic grafted and bottlebrush copolymers will be presented as examples of functional branched architectures accessible through this methodology.
