Dynamics of local stiff linear polymers in solutions of high viscosity solvents
A simple theoretical approach to calculation of dynamic response of local stiff linear polymer chain in semidilute solutions of high viscosity solvents is presented. Using an extended version of the bead-spring hopping model proposed by Jones et al. [J Polym Sci, Phys Ed 1978;16:2215], the dynamic parameters such as: the relaxation time spectra, dynamic shear viscosity eta(omega)/c(p), complex elastic modulus G*(omega) and dielectric constant epsilon(omega) were calculated in the non-free-draining limits. They are shown to be dependent on the polymer concentration c, and the solvent effective viscosity eta (eff) This relationship is compared with experimental data published elsewhere.
