TL;DR: In this paper, enantiomeric poly(lactide)s were assembled on a quartz crystal microbalance (QCM) substrate, which detects the mass of the polymers from the frequency shift, following immersion of QCM into alternating acetonitrile solutions.

TL;DR: In this paper, a wide-angle X-ray diffraction of the drawn polypropylene (PP) films in edge view showed that the α and β crystals are oriented in directions parallel and perpendicular to the drawing directions, respectively.

TL;DR: The copolymerization of 3-(S)-[(benzyloxycarbonyl)methyl]-1,4-dioxane-2,5-dione (BMD) and l -lactide (LAC) was carried out in bulk at relatively low BMD/LAC feed ratios with stannous 2-ethylhexanoate as the catalyst.

TL;DR: In this paper, a di-stereoblock polylactides (di-sb-PLA: PLLA-b-PDLA) having high molecular weight (Mn > 100 kDa) were successfully synthesized by two-step ring-opening polymerization (ROP) of L- and D-lactide using tin(2-ethylhexanoate) as a catalyst.

TL;DR: A mixed suspension of the enantiomeric B-A-B triblock copolymers, polyoxyethylene- block-poly(L-lactide)-block-polyoxyethylenes (PEG-PLLA-PEG) and polyoxy methylene-block- poly(D-lactoride)- block- Polyethylene (P EG-PDLA-P EG), was found to induce reversible gel-to-sol transition depending on the polymer concentration
