| titleOfInvention |
Process for preparing polyether carbonate polyols having primary hydroxyl end groups and polyurethane polymers prepared therefrom |
| abstract |
The present invention reacts a starter compound containing an active hydrogen atom with epoxide and carbon dioxide under double metal cyanide catalysis, reacts the resulting product with a cyclic carboxylic anhydride, and then reacts the resulting product with ethylene oxide and a molecule. Reacting in the presence of a catalyst other than a non-cyclic tertiary amine having the same substituent containing at least one nitrogen atom per sugar, polyether carbonate polyol having a primary hydroxyl end group It relates to a manufacturing method of. The present invention also relates to a polyether carbonate polyol obtainable by this method, a composition comprising this polyether carbonate polyol, and a polyurethane polymer based on this polyether carbonate polyol. |
