Molecular weight distribution methods dynamic light scattering

Raczek, J. (1982) A general method for determination of molecular weight distributions by dynamic light scattering. Eur, Pdyrn,], 18, 847. [Pg.229]

A method suitable for the determination of the molecular weight distribution is the dynamic light scattering. The results are completely identical with the results obtained by the gel permeation chromatography because the method is not so sensitive for the low molecular weight part. But the reproducibility is better. [Pg.27]

Siddiqu and Wu [31] used a dynamic laser light scattering method to characterise an unfractionated PI in chloroform at 25 °C. The relatively small angular and concentration dependencies and translational diffusion coefficients measured by this technique enabled the PI to be characterised from only one measurement at a finite concentration and small scattering angle. Thus, this method could be used to characterise the molecular weight distribution of PI from the measured line-width distribution. [Pg.18]
