| 摘 要： | The morphological structure and mechanism of nucleation and growth of Ln-PB and Ni-PBwith different molecular weight were investigated by transmission electron microscopy. The crys-tallization of low molecular weight fraction is primarily from predetermined nuclei, crystallizationfor the high molecular weight fraction is primarily from sporadic nuclei. Two types morphologyof spherulite with different lamellar entanglement have been observed. The entanglement of highermolecular weight fractions are found to be of significance in the morphology and rate of crystallizationof polymer.
