These structures are accessible by a variety of techniques that include atom transfer radical polymerization (ATRP) methods and the use of living cationic polymerization. Tri-arm star structures are accessible by the living cationic growth of three chains from a triamino core structure and dendrimers have been obtained by the growth of structures based on a diaminobutane polypropyleneimine core with polyphosphazene outer branches. ... 

Yuan et al. [165] reported the synthesis of well-defined dendrimer-star, block-comb polymers by the combination of living ring-opening polymerization and atom transfer radical polymerization on the basis of a dendrimer polyester. Star-shaped dendrimer PCLs were synthesized by the bulk polymerization of e-caprolactone with a dendrimer initiator. The dendrimer PCLs tiien were converted into macroinitiators via esterification with 2-bromopropionyl bromide. And the star-block copolymer dendrimer poly(s-caprolactone)-block-poly(2-hydroxyethyl...
