Paper Abstract

A theory for the dynamics of semi-rigid polymers, based on the wormlike chain, has been extended to include hydrodynamic interactions. The hydrodynamic interactions are treated in the preaveraged form using the kernel of Yamakawa and Fujii [Macromolecules 6:407(1973)]. The dynamic equation is solved by perturbation theory to second order for the eigenvalues and to first order for the eigenfunctions. The solutions to a Fokker-Planck equation are used to compute the polarized dynamic light scattering correlation function for a dilute system of wormlike chains. The electric field correlation function decays with dynamics due to translational diffusion, end-over-end tumbling of an elongation axis, and flexing degrees of freedom.
