TL;DR: In this article, the crystal forms of polylactide (PLA) have different band frequencies, correlation field splittings in FTIR spectra and different line shapes, and resonance splitting in solid-state NMR spectra, which become more distinct with cooling to the cryogenic conditions.

TL;DR: Both initial crystalline structure of homocrystallites (hc) and MW influence the heating-induced hc-to-sc transition of HMW racemic blend drastically; the hc/sc transition becomes easier with decreasing Tc and MW, and sc crystallites show smaller long period than their hc counterparts.

TL;DR: As indicated by the synchrotron radiation small-angle X-ray scattering results, the stereoblock copolymer micelles have larger size, micellar aggregation number, core radius, smaller core density, and looser packing of core-forming segments than the isotactic and enantiomerically-mixed copolymers.

TL;DR: In this article, a zinc phenylphosphonate (PPZn) nucleator was used to promote the stereocomplex (sc) crystallization and suppress the homocrystallization (hc) in high-molecular-weight (HMW) PLLA/PDLA racemic blend.

TL;DR: In this article, a self-assemblable aryl amide nucleator was used to promote Stereocomplex (SC) formation and controlled crystal morphology of a high-molecular-weight (HMW) PLLA/PDLA blend.
