原始语种摘要: With c (#br)rystalline polycaprolactone diols (PCL) used as soft segments, and 1,4-butanediol (BDO), dimethylolpropionic acid (DMPA), and N-methyldiethanolamine (MDEA), respectively, used as different pH-sensitive components, (#br) three types of thermal and pH-sensitive polyurethanes (PUs) were prepared by using the block copolymerization technique and are referred to as PU(a), PU(b), and PU(c), correspondingly. Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and differential scanning calorimetry (DSC) were used to study the distinct functional groups of the PUs and their segmented structures. Their thermal and pH stimuli sensitivity were measured by water permeability (WP) and water swelling (WS) tests. Fourier transform infrared analysis...
