## Abstract **Summary:** Well‐defined multi‐arm star block copolymers, polyglycerol‐__block__‐poly(__tert__‐butyl acrylate) (PG‐__b__‐P__t__BA), with average arm‐numbers of 17, 27, 36, 66 and 90 arms, respectively, have been prepared by atom transfer radical polymerization (ATRP) of __t__BA in acet
## Abstract Biocompatible multi‐arm star block copolymers based on poly(L‐lactide) (PLLA) have been prepared by a __core‐first__ approach, using hyperbranched polyglycerol (PG), a polyether polyol, as a polyfunctional initiator. The molecular weight of the hyperbranched initiator‐core was varied fr
Porphyrin-centered star-shaped polymers were synthesized through living cationic ring-opening polymerization of 2-methyl-2-oxazoline employing tetra(p-chloromethylphenyl)porphyrin (CMPP) and its zinc complex as initiators. The polymers were characterized by GPC, 1 H NMR and UV-vis and their properti
