Ring-Opening Polymerization of ε-Caprolactone with BINOL Phosphoric Acid as the Catalyst
BINOL phosphoric acid (BPA) is found to be an efficient cationicorganocatalyst for the living ring-opening polymerization (ROP) of ε-caprolactone(ε-CL) with 1-octanol as the initiator. The living nature of the ROP of ε-CL catalyzed ...

关键字：Poly (ε-caprolactone), Poly(acrylic acid), PH-responsive,
The pH-responsive amphiphilic PCL-b-PAA was synthesized via ATRP of Methoxymethlacrylate (MOMA), a hemiketal ester of acrylic acid, with PCL-Br as macroinitiator, and followed by the hydrolysis of PMOMA segment under a mild condition without the degradability of PCL segment. 1H NMR, GPC,and FTIR were used to characterize the structure of polymers. Subsequently，the self-assembly of PCL-b-PAA was i...
