Process for preparing polyether polyols and polyols prepared therewith |
摘要 |
Polyether polyols suitable for use in preparing rigid polyurethane foam are prepared by a process utilizing imidazole catalysts. The imidazole catalysts do not lose reactivity at higher tempera tures and can be used at higher temperatures to prepare polyols thereby decreasing residence time and energy consumption in polyol production processes. |
