Method of forming a polyether-carbonate polyol using a CO2-philic compound or substituent

摘要

A method of forming a polyethercarbonate polyol enhances incorporation of CO₂ into the polyethercarbonate polyol. The method provides a catalyst including a multimetal cyanide compound. An H-functional initiator, an alkylene oxide, and CO₂ are reacted in the presence of the multimetal cyanide compound in a reactor. The method further provides a CO₂-philic compound or a CO₂-philic substituent. The CO₂-philic compound and substituent enhance incorporation of the CO₂ into the polyethercarbonate polyol and reduce formation of cyclic alkylene carbonates, such as cyclic propylene carbonate, which are undesirable byproducts.
