Equilibration of the segmental dynamics following a thermal perturbation in the vicinity of Tg and chain adsorption under confinement are closely linked. Here we show that segmental equilibration acts as a kinetic precursor to adsorption. T...
Biobased High- Tg Aliphatic Polyethers via the Ring-Opening Polymerization of Dihydrolevoglucosenone-Derived Spiro-Epoxides [0.03%]
