The methodology using living ROP of EO and a chain-end modification reaction to increase the number of the hydroxyl reaction sites twofold was developed to allow the synthesis of a series of dendrimer-like star-branched (PEO)s up to the 8G stage (Feng et al, 2005). The 8G polymer possessed three branches at the core and two branches at the junctions in all generations having an value of 6.50 x lO g/mol IAS) with 384 external 

Given the appropriate choice of hving polymerization and chain-end modification in divergent synthesis, isolation of the polymer in each iterative process is not necessary and
