Time correlation functions in linear-polymer melts based on NMR-relaxation data
A method, using the temperature-time superposition principle, is proposed for the reconstruction of the form of the time correlation functions on the basis of the temperature dependence of the spin-lattice relaxation times. Correlation functions, which characterize the molecular mobility of various...

| Zusammenfassung: | A method, using the temperature-time superposition principle, is proposed for the reconstruction of the form of the time correlation functions on the basis of the temperature dependence of the spin-lattice relaxation times. Correlation functions, which characterize the molecular mobility of various samples of polybutadiene over a wide time interval, has been obtained. |
