A biocompatible linear organic nucleator (EBH) was incorporated into biodegradable linear aliphatic poly(ethylene succinate) (PES) polyester to investigate effect of EBH on crystallization kinetics, aggregated structure and thermal stability of PES. Crystallization kinetic results suggested that EBH enhanced significantly crystallization rate and decreased substantially crystallization time of PES, and EBH is an excellent nucleator of PES. FTIR measurement indicated that hydrogen bond interaction exists between carbonyl group (of crystalline phase) and ester group (of amorphous phase) of PES and EBH. In-situ FTIR results revealed that upon incorporation of EBH, rearrangement of carbonyl group is faster than C-C backbone of PES in crystallization process. Thermal degradation temperature of PES increased in the presence of EBH. EBH had little effect on crystal structure of EBH. Mechanisms on nucleation and enhanced thermal stability of PES were proposed and discussed in detail.

将生物相容性线性有机成核剂（EBH）掺入可生物降解的线性脂肪族聚琥珀酸乙烯酯（PES）聚酯中，以研究EBH对PES结晶动力学，聚集结构和热稳定性的影响。结晶动力学结果表明，EBH显着提高了PES的结晶速率，并显着减少了其结晶时间，并且EBH是PES的良好成核剂。FTIR测量表明，PES和EBH的（结晶相）羰基和（非晶相）酯基之间存在氢键相互作用。原位FTIR结果表明，在结合EBH后，结晶过程中羰基的重排比PES的CC主链要快。在EBH存在下，PES的热降解温度升高。EBH对EBH的晶体结构影响很小。提出并详细讨论了PES的成核机理和增强的热稳定性。
