Improved double metal cyanide (DMC) catalysts are disclosed which comprise a DMC compound, an organic complexing agent, and from about 5 to about 80 wt.% of a polyether polyol that has tertiary hydroxyl groups. Compared with other DMC catalysts, those of the invention have excellent activity for epoxide polymerization, and they can be used to make polyols having very low unsaturation even at high epoxide polymerization temperatures.
