中文摘要 | five narrowly distributed fractions of phenolphthalein poly(ether sulfone) (pes-c) were studied in chcl3 by both static and dynamic laser light scattering (lls) at 25 degrees c. the dynamic lls showed that the pes-c samples contain some large polymer clusters as in previously studied phenolphthalein poly(ether ketone)(pek-c). these large clusters can be removed by a 0.1-mu m filter. our results showed that [r(g)(2)](1/2)(z) = (3.35 +/- 0.13) x 10(-2) m(w)((0.52 +/- 0.03)) and [d] = (2.26 +/- 0.02) x 10(-4)m(w)-((0.54) +/- 0.03)) with [r(g)(2)](1/2)(z), m(w) and [d] being the z-average radius of gyration, the weight-average molecular weight, and the z-average translational diffusion coefficient, respectively. a combination of static and dynamic lls results enabled us to determine d = (2.45 +/- 0.04) x 10(-4)m-((0.55 +/- 0.05)), where d and m correspond to monodisperse species. using this scaling relationship, we have successfully converted the translational diffusion coefficient distribution into the molecular weight distribution for each of the five pes-c fractional the weight-average molecular weights obtained from dynamic light scattering have a good agreement with that obtained from static laser light-scattering measurements. |
