中文摘要 | five different molecular weight phenolphthalein poly(aryl ether ketone) (pek-c) fractions in chcl3 were studied by static and dynamic laser light scattering(lls). the dynamic lls revealed that the pek-c samples contain some large polymer clusters. these large clusters can be removed by filtering the solution with a 0.1-mu m filter. we found that the persistence length of pek-c in chcl3 at 25 degrees c is similar to 2 nm and the flory characteristic ratio, c-infinity is similar to 25. our results showed that [r(g)(2)](1/2)(z) = (3.50+/-0.20) x 10(-2)m(w)(0.54+/-0.01) and [d] = (2.37+/-0.05) x 10(-4)m(w)(-0.55+/-0.01), 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 = (2.20+/-0.10) x 10(-4)m(-0.555+/-0.015), where d and m correspond to monodisperse species. using this calibration between d and m,we have determined molecular weight distributions of five pek-c fractions from their corresponding translational diffusion coefficient distribution. |
