中文摘要by using different catalyst systems, two trans-1,4-polybutadiene (tpbd) samples with different tr trans-content and molecular weight were synthesized. the phase transition of two samples from monoclinic form to hexagonal phase was revealed by differential calorimeter scanning and x-ray, respectively. the small-angle x-ray scattering measurements showed the remarkable discrepancy of phase transition and melting point between the two samples was attributed to the different lamellar thickness of crystals: the crystals with different crystalline morphology and lamellar thickness were developed by casting different concentration tpbd solutions. transmission electron microscopy morphology observations proved that annealing the specimen at the temperature above the phase transition point for different times resulted in the different lamellae thickening of monoclinic form. it means that annealing the tpbd in its hexagonal phase will also slightly favor the increase of both the phase transition temperature and melting point of hexagonal phase.
