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 (fTMC306), crystallization
temperature (Tc), crystallization rate (k) and degree of crystallinity (Xc) of PES enhanced significantly and
crystallization half-time (t1/2) reduced substantially. However, Tc, k and Xc declined progressively in the presence
of higher fTMC306. Based on IR results, it suggested that TMC-306 interacts with –C––
O 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.
