摘要：
The morphology and formation process of interpenetrated spherulites of poly(butylene succinate)/poly(vinylidene choloride-co-vinyl chloride) (PBSU/PVDCVC) blends were investigated by confocal laser scanning microscopy (CLSM). CLSM images showed that the dense fibrils of PBSU spherulites penetrated into the sparse PVDCVC spherulites. For a blend with PBSU content 50% and crystallization temperature T-c = 368 K, the simultaneous growth of PBSU and PVDCVC spherulites was observed. After PBSU fibrils collided with PVDCVC spherulites, they kept growing through PVDCVC spherulites. For a blend with PBSU content 30% and T-c = 363 K, PBSU started to nucleate after PVDCVC spherulites filled the whole space.
