Popis:	Synthesis and properties of a series of graft polyoxyalkylene-polyorganosiloxane block copolymers of various composition and structure were considered, and their surfactant properties were determined. The surface tension (σ) of the compounds obtained is shown to vary from 32.3 to 20.2 mN m−1. In aqueous solutions they behave as very effective surfactants. Thus, in several cases values of σ (19.7 mN m−1) observed were lower than those of organic surfactants (28.6–30.4 mN m−1). Their solutions in water or organic solvents show a significant decrease in wetting angle on glass.
