Synthesis of novel star shaped poly (epsilon-caprolactone) utilizing fullerene as the molecular core

摘要

The synthesis of star shaped poly(epsilon-caprolactone) (PCL) with a fullerene molecular core (s-PCLF) was successfully achieved by the ring-opening polymerization of epsilon-caprolactone with fullerenol as the initiator. Through NMR and GPC analysis, the average number of arms of PCL on each fullerene core was estimated to be 2-3.
