The viscoelasticity of a stretched polymer chain with its end particles exposed to oppositely acting forces is studied via collisional molecular dynamics and analytically. A simple model according to which a polymer molecule is a chain of particles l

We study the extension of semiflexible (persistent) polymer chains composed of elastic bonds under the action of forces applied to their ends. For a given discrete model of a chain, the effective potential energy includes three components: the energy

A relatively simple formula for the mean distance between the ends of a model chain composed of elastic freely joined segments as a function of an extending force applied to its ends was derived. It was assumed that the stiffness coefficient, which c

The viscoelasticity of stretched polymer chains has been studied by the method of collisional dynamics. To this end, time correlation functions of the fluctuations of the microscopic stress tensor are modeled and relaxation moduli are expressed. Befo

The thermal diffusion coefficient in highly diluted polymer solutions is calculated. The pearl necklace model is used for description of flexible macromolecule dynamics. It is assumed that the usual diffusion equation holds under non-uniform temperat

Based on the previously developed molecular theory, we analyze experiments in which a small periodic deformation is applied to a statically extended elastomer and then the dynamic modulus is measured as a function of the static extension ratio λ. Th

A theory of NMR of protons belonging to highly-stretched polymer chains with fixed ends, e.g. tie molecules of amorphous regions of oriented semicrystalline polymers, is presented. Analysis is carried out in terms of the model of freely-jointed chain
