Abstract Proceedings of the European Conference on Constitutive Models for Rubber, Dresden, 7-10 September 2009<br /><br />A freely-jointed-rods chain model and a modified Rouse model are used to study molecular mobility and dynamic mechanical properties of strongly stretched polymer chains and networks. Stretched polymer chains and networks are characterized by the anisotropy of dynamic mechanical properties: frequency dependent storage and loss shear moduli are different for different geometries of applying the shear gradient (parallel or perpendicular to the axis of deformation) and display several plateaus (or maxima), whose positions depend on the static strain. Theoretically calculated frequency dependences of the loss and storage moduli are in an agreement with experimental data.<br /><br />ISBN 978-0-415-56327-7
