A polyethercarbonate polyol includes polyethercarbonate segments, polycarbonate segments, and polyether segments. A method of forming the polyethercarbonate polyol provides a catalyst, including a multimetal cyanide compound, and reacts an H-functional initiator, an alkylene oxide, and carbon dioxide in the presence of the multimetal cyanide compound to form the polyethercarbonate polyol. Amounts of each segment in the polyethercarbonate polyol are selectively controlled.
