Polysiloxane-polyoxyalkylene block copolymers as stabilizers in the production of urethane foam

摘要

Polyoxyalkylene polyether admixtures and polysiloxane-polyoxyalkylene block copolymers, a solventless process for producing said copolymers using said admixtures, a process for producing flexible polyether polyurethane foam using said copolymers as foam stabilizers and the foam produced thereby.
