## Abstract The photooxidative degradation of acrylic fibers was investigated with two different fiberβspinning processes, that is, dry spinning and wet spinning. Several analytical methods were used in this study: viscometry, Xβray diffraction, Fourier transform infrared spectroscopy, optical meas
Two series of thermoplastic polyurethane elastomers were synthesized from 4,4Π-methylenediphenyl diisocyanate (MDI), 1,4-butanediol (BDO) chain extender, and each of poly(tetramethylene oxide) (PTMO) and poly(hexamethylene oxide) (PHMO) macrodiols. The PTMO and PHMO molecular weights were kept const
