摘要：Polysiloxane-polyether copolymer having at least one polyether group exhibiting at least one ether terminal building block (I), is new. Polysiloxane-polyether copolymer having at least one polyether group exhibiting at least one ether terminal building block of formula (-O-C(O)-O-R11) (I), is new. R11 : alkyl. Independent claims are also included for: (1) preparing the polysiloxane-polyether copolymer; (2) use of the polysiloxane-polyether copolymer as foam stabilizers in the production of polyurethane foams and in the production of polyurethane-based plastics, as surfactants for liquid carbon dioxide extraction, as surface-active substances in dry-cleaning, and as emulsifiers for cosmetic applications; and (3) the polyurethane foam comprising at least one above polysiloxane-polyether copolymer.
