| 中文摘要 | local main chain dynamics of dissolved phenolphthalein polyethersulfone (pes-c) in solution with chloroform-d(1) were examined through c-13 nmr relaxation measurements. spin-lattice relaxation times and noe (nuclear overhauser effects) factors were measured as a function of temperature. the relaxation data were interpreted in terms of main chain segmental motion by using the damped orientational diffusion model (damp) and the conformation jump model (vjgm) derived by valeur, jarry, geny, and monnerie. the simulation method used is n-simplex, which gives, in this study, a result of the object function less than 10(-4). correlation times were obtained for the main chain motion of pes-c with these models and the results indicate that the main chain of pes-c are flexible. the comparison between pes-c and 1,2-polybutadiene is proposed. the distribution of the correlation time for the main chain motion by using vjgm model is discussed. the temperature dependence of correlation times for pes-c indicating the dynamical rigidity of its chains is obtained. |
