A linear diamides derivative-containing organic compound (TMC306) as a nucleator was incorporated into biodegradable poly (ethylene succinate) (PES) to investigate effect of TMC306 on crystallization behavior and aggregated structure of PES. Upon incorporation of TMC306 with lower weight fraction (f_TMC306), crystallization temperature (T_c), crystallization rate (k) and degree of crystallinity (X_c) of PES enhanced significantly and crystallization half-time (t_1/2) reduced substantially. However, T_c, k and X_c declined progressively in the presence of higher f_TMC306. Based on IR results, it suggested that TMC-306 interacts with –CO group of PES and C–O–C group of PES amorphous phase via hydrogen bond. Mechanisms on nucleation of PES and dual effects of TMC306 on crystallization behavior of PES were proposed and discussed in detail.

将含有线性二酰胺衍生物的有机化合物（TMC306）作为成核剂掺入可生物降解的聚琥珀酸乙烯酯（PES）中，以研究TMC306对PES结晶行为和聚集结构的影响。加入较低重量分数的TMC306（f _TMC306），_PES的结晶温度（T _c），结晶速率（k）和结晶度（X _c）大大提高，结晶半衰期（t _1/2）大大降低。 。但是，T _c，k和X _cf _TMC306较高时_逐渐下降。根据红外结果，表明TMC-306通过氢键与PES的–C O基和PES非晶相的C–OC–C基相互作用。提出并详细讨论了PES成核机理和TMC306对PES结晶行为的双重影响。
