Abstract: Stereocomplex crystals of polylactide and graphene oxide (GO) were simultaneously used to regulate the mechanical properties and heat resistance of a poly(l-lactide-co-trimethylene carbonate) [P(LLA-co-TMC)] copolymer. The crystallization behaviors in the nonisothermal cold-crystallization process of P(LLA-co-TMC)–poly(d-lactide)… read more here.

DOI: 10.1002/app.45575
Abstract: Supramolecular poly(ɛ-capolactone)/poly(lactide) alternating multiblock copolymers were prepared by UPy-functionalized poly(lactide)-b-poly(ɛ-capolactone)-b-poly(lactide) copolymers. The prepared supramolecular polymers (SMPs) exhibit the characteristic properties of thermoplastic elastomers. The stereo multiblock SMPs (sc-SMPs) were formed by blending UPy-functionalized poly(l-lactide)-b-PCL-b-poly(l-lactide) (l-SMPs)… read more here.
