抄録: 2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO)-terminated prepolymers (TPs) were synthesized by reaction of 4-hydroxy-TEMPO and poly (oxytetramethylene) glycol (PTMG; Mn=1000,3000) with isocyanate groups. TPs were characterized by means of FT-IR, ^1H-NMR, and ESR. Since ESR spectra of TPs displayed a typical three signals based on TEMPO residues, it is found that TPs have the living nitroxyl radical. Stearyl acrylate (SAA) was polymerized by TPs with BPO as an initiator. Properties of the obtained block copolymers were investigated by use of 1 H-NMR spectrometer, GPC, viscometer, DSC, and dynamic viscoelastic tester. The obtained block copolymers were (SAA) n-PU-(SAA) n and a small amount of SAA homopolymer. The properties of these block polymers were affected with molecular weight of PTMG and concentration of SAA.
