摘要： Dispersion polyols which are liquid--liquid dispersions containing a first polyol having a substantially polyoxypropylene internal block having an equivalent weight in excess of about 700 Da and a high oxyethylene-content external block, and a second polyol which is a substantially polyoxyethylene polyol containing minimally 50 weight percent oxyethylene moieties. The dispersion polyols are stable and exhibit broad processing latitude when preparing hypersoft polyurethane foams. The dispersion polyols are advantageously prepared in situ, preferably in the presence of a double metal cyanide oxyalkylation catalyst.

Further improved demold times and elevated elastomer physical properties are made possible by the use of multidisperse polyoxyalkylene polyether polyol blends having an overall unsaturation of less than 0.010 meq/g and a polydispersity of about 1.4 or greater.

摘要： Polyurethane elastomers exhibiting improved green strength while maintaining short demold times are prepared from ultra-low unsaturation polyoxypropylene polyols containing up to 20 weight percent internal random oxyethylene moieties. The elastomers adsorb less than 10 weight percent water at 0.degree. C. The internal polyoxyethylene moiety-containing polyoxypropylene polyols may be used to prepare ultra-low unsaturation polyoxyethylene capped polyols which are haze-free and which may be used to prepare haze-free 4,4'-MDI prepolymers. Multidisperse blends of monodisperse internal oxyethylene moiety-containing polyoxypropylene polyols of ultra-low unsaturation provide yet further improvements in elastomer processing.
