Tadpole shaped poly(ethylene glycol)-b-polycaprolactone (PEG-b-PCL) could be successfully prepared by the combination of ring-opening polymerization(ROP) and click reaction. The synthesis can be achieved in two main steps: first preparation of a linear alkyne-terminated PEG-b-PCL diblock with an azide group attached at the junction between two blocks. Next, intramolecular cyclization of polycaprolactone block using click reaction under high dilute condition. The MALDI-TOF spectra and GPC confirm the tadpole polymer architecture and all polymer maintain a low dispersity
