| Abstract: | Three series of diisocyanates derived from block copolymer are prepared. The oil/water interfacial tensions, the lifetime of the droplets on the flat oil/ water interface, and the de- emulsifying power are measured. The influence of the adsorbed state of their molecule at oil/ water interface on the demulsifying power and the mechanism of de- emulsification a re discussed. |
