The synthesis of linear and crosslinked polyurethanes based on α,ω-dihydroxypolydiethylene glycol terephthalate (PDET) is described. Prior to the preparation these materials, a PDET polymer was obtained by conventional condensation reaction between dimethyl diethylene glycol, well-characterized fraction with number average molecular weight 3,650 g mol−1 chosen for polyurethanes. Specifically, t...

Potentially high-performance lithium metal cells in extreme high-temperature electrochemical environments is a challenging but attractive battery concept that requires stable and robust electrolytes to avoid severely limiting lifetimes of the cells. Here, properties tailored polyester polycarbonate diols as soft segments polyurethanes are investigated electrochemically evaluated for use solid p...

An innovative and eco-friendly one-pot synthesis of bio-based polyurethanes is proposed via the epoxy-ring opening of epoxidized soybean oil (ESO) with methanol, followed by the reaction of methoxy bio-polyols intermediates with 2,6-tolyl-diisocyanate (TDI). Both synthetic steps, methanolysis and polyurethane linkage formation, are promoted by a unique catalyst, molybdenum(VI) dichloride dioxid...
