Mechanical Excitation and Scission of a Chain

  • Hans-Henning Kausch-Blecken von Schmeling
Part of the Polymers book series (POLYMERS, volume 2)


A chain molecule as part of a thermoplastic body is in thermal contact with other chains and — at room temperature — constantly in motíon. The atoms vibrate and take part in the more or less hindered rotations of groups and even of chain segments. With no external forces acting all molecular entities try to approach — and fluctuate around — the most stable positions attainable to them. The action of external forces causes — or maintains — displacements of the chain from those positions and evokes retractive forces. Let us consider a chain or a bundle of chains in thermal contact with the surrounding and at constant volume. The condition of thermodynamic stability of such a system is that the free energy
$$F = U - TS$$
assume a minimum. The differential changes of the free energy of the system are given by the changes of its internal energy U and its entropy S.
