A novel 5-arm star shaped block copolymer consisting of an poly(ethylene glycol) inner block and an poly(e-caprolactone) outer block was prepd. by utilizing an 5-arm star shaped poly(ethylene glycol) macroinitiator for the controlled ring opening polymn. of e-caprolactone. Furthermore, the resulting polymer was functionalized with terpyridine metal binding sites. The resulting new star shaped supramol. block copolymer combines several specialties in one macromol.: the star shaped form, block copolymer properties as well as metal binding sites, which might lead to interesting applications
