关键字：Thermoresponsive, Star Amphiphilic Block Copolymer, Self-assembly, Specific Recognition
A novel star amphiphilic block copolymer star poly(caprolactone)-b-poly(N-isopropylacrylamide-co-N,N-dimethylacrylamide)-DDAT [SPCL-b-P(NIPAAm-co-DMAAm)-DDAT] was synthesized by combination of ring-opening polymerization (ROP) and reversible addition-fragment chain transfer (RAFT) polymerization. The DDAT-terminated groups was further transformed into hydroxyl groups by one-pot strategy for aminol...

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...
