説明
Fifteen fractionated samples of poly(terephthalamide-P-benzohydrazide) (PPAH) ranging in weight-average molecular weight from 2×103 to 6×104 were studied by light scattering, sedimentation equilibrium, and viscometry with dimethyl sulfoxide (DMSO) at 25°C as the solvent. The data obtained for the radius of gyration, the optical anisotropy factor, and the intrinsic viscosity showed the PPAH chain in DMSO to be semiflexible. Analysis of these data in terms of current theories for the Kratky–Porod wormlike chain gave 11.2±0.5 nm, 185±5 nm−1, 0.5 nm, and 2.1 for the persistence length, molar mass per unit contour length, diameter, and optical anisotropy [= 3(α1–α2)/(α1+2α2)] of the PPAH chain in DMSO, respectively. Here, α1 and α2 are, respectively, the longitudinal and transverse polarizabilities per unit contour length of the chain.
