    Description / Table of Contents: The rupture of macromolecules subjected to mechanical stress, which contain foreign atoms in the chain, was investigated. The potential barrier for the rupture of the chain is calculated, considering stress, temperature and mass defect. The occurence of local vibrations and resonance levels in the vibrational spectrum may be combined with remarkable changes in the activation energy for the rupture of bonds.
    Notes: Das Reißen mechanisch beanspruchter Makromoleküle, die in der Kette Fremdatome enthalten, wird untersucht. Die Potentialbarriere für den Bruch der Polymerkette wird in Abhängigkeit von der Spannung, der Temperatur und dem Massendefekt berechnet. Dabei zeigt sich, daß das Auftreten von lokalen Schwingungen und Resonanzniveaus im Schwingungsspektrum zu einer merklichen Änderung der Aktivierungsenergie für den Bruch der Bindungen führen kann.
