With the increased development and consumption of polyurethane, the polyether polyols which is an important raw material also developed rapidly. The demand of polyether polyols was also increased. Associated with the production of polyether polyols is the rapid development of technology, and the continuous improvement of the catalyst is an important factor in the development of polyether polyols. Based on the recent classification of catalyst used during the production of polyether polyols, the status of research of the catalyst used in polyether polyols preparation is reviewed. The preparation process of catalysts, the catalyst used during the production of polyether polyols are narrated. In addition, some advises concerning the development of the applied technology are given out.
