Abstract: Polysiloxanes bearing polyether groups (polyether/polysiloxane)，as one of the important functional polysiloxanes，have been widely used for textile hydrophilic antistatic finishing，or as foam stabilizers in production of polyurethane resin，anti-foam agent，personal care and so on. Firstly，the classification，synthesis and applications of polyether/polysiloxane in various industrial processes，especially in some high-tech fields，e.g. biomedical materials，are summarized，then the modified products，such as amino，saccharide，polyurethane，benzophenone derivatives，carboxyl group modified polyether/polysiloxanes as well as the alkali metal chelated polyether/polysiloxanes，and their new developments in pesticide auxiliaries，high-energy battery electrolytes and so on，are introduced in detail.
