    Simultaneous small-angle X-ray scattering/wide-angle X-ray diffraction study of the microdomain structure of polyurethane elastomers during mechanical deformation

    Polyurethane elastomers (PUEs) were prepared with poly(oxytetramethylene) glycol (Mn=2000), 4,4′-diphenylmethane diisocyanate, 1,4-butanediol (BD) and 1,1,1-trimethylol propane (TMP) by a prepolymer method. To ev...

    Poly(2,5-benzimidazole) nanofibers prepared by reaction-induced crystallization

    Morphological control of poly(2,5-benzimidazole) (PBI) was examined by reaction-induced phase separation of oligomers during polymerization to prepare nanofibers. Three monomers, 3,4-diaminobenzoic acid (DABA)...
