Abstract The origin of rebound suppression an impacting droplet by a small amount polymer additive has been tentatively explained various physical concepts including the dynamic surface tension, additional energy dissipation non-Newtonian elongational viscosity, elastic force stretched polymer, and friction on receding contact line. To better understand role molecular level, we performed multi-...

Polylactide (PLA) is the leading bioderived polymer produced commercially by the metal-catalyzed ring-opening polymerization of lactide. Control over tacticity to produce stereoblock PLA, from rac-lactide improves thermal properties but is an outstanding challenge. Here, phosphasalen indium catalysts feature high rates (30±3 m-1  min-1 , THF, 298 K), high control, low loadings (0.2 mol %), and ...

The compatibility between polymer and surfactant solutions is the main parameter for the optimisation of this combination method. In order to obtain the sufficient viscosity and the low interfacial tension of these solutions, it is necessary to know the conditions under which the different additives are compatible. We have studied the monophase to diphase transition of the system, the critical ...
