英文摘要	Well-defined amphiphilic polymethylene-b-poly(e-caprolactone)-b-poly(acrylic acid) (PM-b-PCL-b-PAA) triblock copolymers were synthesized via a combination of polyhomologation, ring-opening polymerization (ROP), and atom transfer radical polymerization (ATRP). First, hydroxyl-terminated polymethylenes (PM-OH; Mn = 1100 g mol-1; Mw/Mn = 1.09) were produced by polyhomologation followed by oxidation. Then, the PM-b-PCL (Mn = 10,000 g mol-1; Mw/Mn = 1.27) diblock copolymers were synthesized via ROP of e-caprolactone using PM-OH as macroinitiator and stannous octanoate (Sn(Oct)2) as a catalyst. Subsequently, the macroinitiator transformed from PM-b-PCL in high conversion initiated ATRPs of tert-butyl acrylate (tBA) to construct PM-b-PCL-b-PtBA triblock copolymers (Mn = 11,00014,000 g mol-1; Mw/Mn = 1.241.26). Finally, the PM-b-PCL-b-PAA triblock copolymers were obtained via the hydrolysis of the PtBA segment in PM-b-PCL-b-PtBA triblock copolymers. The chain structures of all the polymers were characterized by gel permeation chromatography, proton nuclear magnetic resonance, and Fourier transform infrared spectroscopy. Porous films of such triblock copolymers were fabricated by static breath-figure method and observed by scanning electron microscope. The aggregates of PM-b-PCL-b-PAA triblock copolymer were studied by transmission electron microscope. (c) 2012 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2012
