Synthesis and Characterization of a Novel Star-Shaped Polymers with Biological Compatibility via Ring-Opening Polymerization and Atom Transfer Radical Polymerization
Abstract:
Hydroxyl functional hyperbranched polyester initiators initiated the ring-opening polymerization(ROP) of ε-caprolactone (CL) and the star-shaped polymer with PCL arms using hyperbranched polyester as nuclear was produced. Then, the bromide of star-shaped polymer, initiated the atom transfer radical polymerization (ATRP) of oligo(ethylene oxide) methacrylate (OEOMA) and the star-shaped polymer containing the arms of PCL-b-POEOMA was synthesized ,and the characterization of polymer structure was investigated by NMR.
