“…The relatively low-intensity peaks around 19-22 • match the diffraction of poly(butylene succinate) (PBS), particularly the peaks at 2θ = 19.4 • and 22.2 • , corresponding to the (020) and (110) crystallographic planes, respectively [50]. Another low-intensity peak was observed at around 16.7 • , and it could be attributed to the PLA fraction of the polymer blend, in particular the (200) crystallographic plane, as has already been reported by other authors [51].…”

“…4a , a typical spherulitic morphology with Maltese cross could be observed for pure PLA. 50,51 Small number of spherulites with large size and clear interfaces between crystalline region and amorphous region were found in the POM image of PLA, which was a typical homogeneous nucleation. 52 After the chain extension reaction between PLA and POE- g -GMA, the number of spherulites increased significantly and the spherulite size decreased.…”

“…The effect of TCB on the crystallization behaviour of PLA was studied on a molecular level by time-resolved FTIR and wide angle X-ray diffraction [ 38 ]. The observed vibrational changes indicate that the arylamide molecules can accelerate the formation of a skeletal conformational-ordered structure but their presence is more favourable to the formation of a 10 3 helix structure that is characteristic of α and α’ crystals.…”
