Summary: RAFT is applied to the dendronized macromonomers of the first and second generation, 1 and 2, respectively. Good results are obtained in the presence of AIBN as radical initiator, with compound 6 as mediator and at mediator to monomer ratios of 2:200 for monomer 1 (equation image = 320 000, PDI = 1.24) and monomer 2 (equation image = 178 000, PDI = 1.20). The common characteristics of a controlled polymerization are reasonably met. The more sterically demanding G2 monomer 2 requires higher polymerization temperatures.
