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 η(ω)/cp, complex elastic modulus G∗(ω) and dielectric constant ε(ω) were calculated in the non-free-draining limits. They are shown to be dependent on the polymer concentration cp and the solvent effective viscosity ηeff. This relationship is compared with experimental data published elsewhere.
