| titleOfInvention | Methods of making low unsaturation polyether polyols |
| abstract | There is provided a method of making the polyoxyalkylene polyether polyol by reacting in the presence of a catalyst an initiator compound having at least two sites reactive with an alkylene oxide, directly or indirectly in sequential order, propylene oxide to form an internal block of oxypropylene groups, followed by reacting directly or indirectly onto the block of oxypropylene groups one or more second oxide compounds, at least one of which is a C4 or higher alkylene oxide, to form a second block of oxyalkylene groups. The amount of propylene oxide added is advantageously from 25 weight percent to 80 weight percent, based on the weight of all oxyalkylene compounds added to the initiator and the initiator, and the amount of the one or more second oxide compounds, at least one of which is a C4 or higher alkylene oxide, should be effective to reduce the unsaturation of the polyether polyol to 0.06 meq KOH/g of polyol or less. |
