| Summary: | 碩士 === 國立中央大學 === 化學學系 === 83 === The microstructure, and morphology determined the physical pro-
perties of polymers. For example, the difference in weight
frac- tion crystalline,amorphous and the interfacial domains
would produce polymer suitable forentirely different
application. This methods are demonstrated in a series of
polyethylene polymer of different commoner units from different
catalysts systems and the molecular microstructure of each
polymers are well characterized by solution NMR and IR.These
results indicated that The results confirmed the novel NMR
approach using relaxation dispersion can be a convenient and
efficient tool for polymer which provide information not
accessible through conventional tests for multipledomain
polymer systems.
