Hyperbranchedpolymers with a degree of branching of 100% were prepared by catalyst transfer Suzuki-Miyaura polymerization of AB(2) monomers carrying one boronic acid and two aromatic bromo functional groups; in contrast, Suzuki-Miyaura polymerization of the same AB(2) monomers using a traditional catalyst afforded hyperbranchedpolymers with a branchingdegree of only approximately 56%. This is a
