摘要：

Poly(butylene succinate-co-butylene carbonate)/poly(L-lactic acid) (PEC/PLLA) blends are crystalline/crystalline polymer blends with close melting temperatures. We investigated the miscibility and the crystallization behavior of PEC/PLLA blends by differential scanning calorimetry and polarized optical microscopy. At certain blend compositions and crystallization temperatures, both components crystallized simultaneously. Under those conditions, PEC spherulites continued to grow after the collision with PLLA spherulites, while PLLA spherulites stopped growing.
