Dynamic light scattering behaviour in the form of periodic oscillating correlation functions has been found from measurements on both physically and chemically crosslinked hydrogels. The former were aqueous methyl cellulose at the thermal gelation temperature and the latter were poly(N,Ndimethylacry

โฆ Synopsis
Applications of both polarized and depolarized dynamic light scattering to the study of polymers are described. Polarized light scattering is used to study translational diffusion, diffusion virial coefficients, rotational motion of long rod-shaped polymers, longwavelength intramolecular motions, dynamics of pseudogels and gels and density fluctuations in bulk polymers. Depolarized scattering is used to study rotational diffusion of rigid macromolecules, local and long-wavelength intramolecular motions, dynamics in semi-dilute solutions, rotational motion of small molecules in glassy polymers and optical anisotropy fluctuations of bulk polymers.

Dynamic light-scattering measurements were carried out for collagen in acetate buffer (pH 4.8) extracted from lathyritic ratskin. The correlation functions were analyzed in terms of the semiflexibility of collagen molecules. The experimental T / K vs K relationship was compared with the theoretical
From the scattered intensity as a function of scattering wave number, local ordering in concentrated latex dispersions in benzene is found. Fmm the combination of intensity and photon correlation experiments follows the existence of strong hydrodynamic interactions between the dispersed particles.
