Super tough biobased poly(ethylene 2,5-furandicarboxylate) materials: synthesis and thermo-mechanical properties of poly(ethylene 2,5-furandicarboxylate-mb-poly(tetramethylene glycol)) multiblock copolymers.
Poly(ethylene 2,5-furandicarboxylate) (PEF) is a biobased polyester with superior thermo-mechanical and gas barrier properties than poly(ethylene terephthalate) (PET), the most widely used petroleum-based polyester. However, PEF is more brittle than PET. To toughen PEF, a series of P(EF-mb-PTMG) (PETF) multiblock copolymers with high intrinsic viscosity were successfully synthesized via melt pol...

In vitro degradation of biodegradable blending materials based on poly(p-dioxanone) and poly(vinyl alcohol)-graft-poly(p-dioxanone) with high molecular weights
Amphiphilic biodegradable graft copolymer, poly(vinyl alcohol)-graft-poly(p-dioxanone) (PVA-g-PPDO), was used to prepare a new biodegradable material by blending with poly(p-dioxanone) (PPDO). The in vitro degradation properties of the copolymer and blends with different contents of PVA-g-PPDO were studied in phosphate buffer at 37 degrees C. The degradation processes of the PVA-g-PPDO and its ble...

Core-shell-corona micellar complexes between poly(ethylene glycol)-block-poly(4-vinyl pyridine) and polystyrene-block-poly(acrylic acid)
onlinelibrary.wiley.com/doi/10.1002/macp.200500368/abstract
The complexation between polystyrene-block-poly(acrylic acid) (PS-b-PAA) micelles and poly(ethylene glycol)-block-poly(4-vinyl pyridine) (PEG-b-P4VP) is studied and a facile strategy is proposed to prepare three-layered core–shell–corona micellar complexes. Micellization of PS-b-PAA in ethanol gives rise to spherical core&nda...
