英文摘要	two types of polylactide-poly(butylene adipate-co-terephthalate)-polylactide (pla-pbat-pla) tri-block copolymers with different molecular weights (cp1 and cp2) were synthesized as compatibilizers for pla/pbat blends. synergistic effects of cp1 and cp2 on the mechanical and rheological properties of the blends have been studied in detail. the addition of small amounts of cp1 and cp2 remarkably increased the elongation at the break point. 0.5 and 0.5 wt% of cp1 and cp2 led to an increase of elongation by over eightfold. thermal, morphological and rheological analyses showed that addition of cp1 and cp2 increased the miscibility and interfacial bonding strength between pla and pbat, in addition to decreasing the melt viscosity. it was thought that the low-molecular-weight compatibilizer cp1 with high mobility would have a positive effect during the transportation of the high-molecular-weight cp2 from the matrix to the interface. in addition, cp2 played a key role in improving the interaction at the interface.
