Lignin-based polyols (LBPs) with controlled microstructure were obtained by cationic ring opening polymerization (CROP) of oxiranes in an organosolv lignin (OL) tetrahydrofuran (THF) solution. The control on the microstructure and consequently on the properties of the LBPs such as hydroxyl

In this study, a new pH-tunable thermoresponsive hydroxyl-terminated hyperbranched polyether (HTHP 2) was successfully prepared via a one-pot cationic polymerization technique and postmodification. In the first step, hydroxyl-terminated hyperbranched polyether containing double bonds (HTHP 1) were synthesized. Then, through thiol-ene

Fatty acid esters of glycidol (glycidyl esters) are heat-induced food contaminants predominantly formed during industrial deodorization of vegetable oils and fats. After consumption, the esters are digested in the gastrointestinal tract, leading to a systemic exposure to the reactive epoxide

Herein, hyperbranched poly(ethylene glycol)-based supramolecular nanoparticles with pH-sensitive properties were designed and used for targeted drug delivery. Via host-guest recognition between benzimidazole anchored poly(ethylene glycol)-hyperbranched polyglycerol (PEG-HPG-BM) and folic acid modified CD (FA-CD), targeted supramolecular nanoparticles (TSNs) were fabricated.

Glycidyl esters (GEs) are known to be formed during vegetable oil processing. Because of their structure, it has been hypothesised that GEs, like fatty acid esters of chloropropanols (MCPD esters), may be accepted as substrates by gut lipases to release
