Investigation of slow dynamic processes in amorphous and crystalline polymers by 1D-MAS NMR spectroscopy

The investigation of slow molecular dynamics in several polymers (amorphous and semicrystalline) by 1D-MAS exchange NMR methods, was the aim of this work. In this work, new 1D-MAS exchange experiments are described together with the results obtained, for polymers, ranging from amorphous to semicrystalline polymers. For the relevance of the results obtained with these methods, the experimental data were always correlated with those obtained from other experimental techniques like dielectric spectroscopy, mechanical relaxation, DSC, HCS, etc. (orig.)SIGLEAvailable from: <a href=http://sundoc.bibliothek.uni-halle.de/diss-online/03/03H063/prom.pdf target=NewWindow>http://sundoc.bibliothek.uni-halle.de/diss-online/03/03H063/prom.pdf</a> / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekDEGerman
