A blending procedure utilizing a crystallized, tough, biodegradable poly(lactic acid) (PLA) blend with poly(trimethylene terephthalate) (PTT) and reactive compatibilizer, poly(ethylene-co-glycidyl methacrylate) (PEGMA), produced by two-step blending, was investigated in this research. The effects of the reactive compatibilizer and annealing temperature were investigated using an annealing PLA/PTT/PEGMA blend. The tensile properties of the annealed PLA/PTT/PEGMA blend were drastically improved compared with the annealed neat PLA and PLA/PTT blends. Craze formation was observed in the elongated area of the annealed PLA/PTT/PEGMA blend, and it was suggested to contribute to the toughening of the blend. The crystal's lack of spherulitic morphologies also contributed to the improved tensile properties, as confirmed by polarized optical microscopy (POM) and small-angle light scattering (SALS). The crystallization kinetics of the blends during annealing were also studied. Moreover, hydrolytic degradation of the blend could be controlled, after blending with PTT and PEGMA.

利用结晶化，坚韧，可生物降解的聚（乳酸）与聚（对苯二甲酸丙二醇酯）（PLA）共混物（PTT）和反应性增容剂，多聚A掺混过程（乙烯-共本研究研究了通过两步共混制备的甲基丙烯酸-环氧丙酯（PEGMA）。使用退火PLA / PTT / PEGMA共混物研究了反应性增容剂和退火温度的影响。与退火的纯PLA和PLA / PTT混合物相比，退火的PLA / PTT / PEGMA混合物的拉伸性能得到了显着改善。在退火的PLA / PTT / PEGMA共混物的细长区域中观察到了裂纹形成，并表明有助于共混物的增韧。如偏光光学显微镜（POM）和小角度光散射（SALS）所证实，晶体缺乏球晶形态也有助于改善拉伸性能。还研究了共混物在退火过程中的结晶动力学。此外，
