Polyurethane foam prepared by using novel surfactant

The invention discloses a novel polyurethane foam which is prepared from a category of novel polysiloxane surface-active agents, wherein these surface active agents contain high molecular weight polyether with narrower molecular weight distribution than the conventional polyethers, these polyethers...

Beschreibung
Zusammenfassung:	The invention discloses a novel polyurethane foam which is prepared from a category of novel polysiloxane surface-active agents, wherein these surface active agents contain high molecular weight polyether with narrower molecular weight distribution than the conventional polyethers, these polyethers are prepared at the presence of bimetallic cyanides as catalyst.
