POLYSILOXANE POLYETHER COPOLYMERS HAVING (POLYETHER)MOIETIES COMPRISING CARBONATE GROUPS AND THEIR USE AS STABILIZERS FOR THE PRODUCTION OF POLYURETHANE FOAMS

摘要

The present invention relates to polysiloxane polyether copolymers which comprise at least one (polyether) moiety which comprises at least one unit —O—C(O)—O—, to a process for the production of the polysiloxane polyether copolymers, and also to the use of the polysiloxane polyether copolymers as stabilizers in the production of polyurethane foams, and also to polyurethane foams and items therefrom which are obtainable through the process.
