Abstract: Polyethers are prepared by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound that has at least one hydrocarbyl substituent, and a cyclic amidine. The phosphorus-nitrogen base is present in only a small molar ratio relative to the amount of starter. The presence of such small amounts of cyclic amidine greatly increases the catalytic activity of the system, compared to the case in which the aluminum compound is used by itself. The product polyethers have low amounts of unsaturated polyether impurities and little or no unwanted high molecular weight fraction. Polymers of propylene oxide have very low proportions of primary hydroxyl groups.

Abstract: Alkoxylations are performed by reacting a cyclic oxide with a starter in the presence of certain phosphonium catalysts. The phosphonium catalysts are highly active and effective in such small quantities that it is often unnecessary to remove catalyst residues from the product. The phosphonium catalysts are very effective in alkoxylating even low molecular weight starters such as glycerol and sorbitol.
