TL;DR: In this article, the stereocomplex formation between a poly(L-lactide) (100L) having an enantiomeric excess of 100% and a poly (D-lactic) (80D)-poly(D-poly(L)-polylactides) having enantiomeoric excess of 80% (20D) has been investigated using differential scanning calorimetry and optical microscopy, and the melting temperatures of blends 100L/100D and 100D/80D are 230 and 208 °C, respectively.

TL;DR: In this paper, a functional group X associated with the active alcoxy group of the initiator is selectively and quantitatively attached to one chain, whereas the second end group is systematically a hydroxyl function.

TL;DR: In this paper, a macromonomer was incorporated into the polymeric backbone to give block copolymers of controlled molecular weight and narrow polydispersities. But the graft copolymerization mixture was also used to give graft systems with a variety of functional groups attached to the backbone.

TL;DR: In this article, the effect of Lewis bases on transesterification reactions has been investigated and discussed in reference to the "coordinationinsertion" mechanism, which is used in e-caprolactone ring-opening polymerization.

TL;DR: Stereocomplex crystallization into miscible PLLA/PDLA/PMMA blends represents a relevant approach to developing transparent, heat-resistant, and partly biobased polymers using conventional injection-molding processes.
