Latest Patents

Waller holds a patent for "Alkylene oxide polymerization using aluminum compounds and phosphorus-nitrogen bases." This patent describes a process for preparing polyethers by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound with at least one hydrocarbyl substituent, and a phosphorus-nitrogen base. The method emphasizes the use of small molar ratios of the phosphorus-nitrogen base, which significantly increases the catalytic activity of the system compared to using the aluminum compound alone. The resulting polyethers exhibit low levels of unsaturated polyether impurities and minimal unwanted high molecular weight fractions. Notably, polymers of propylene oxide produced through this method have very low proportions of primary hydroxyl groups.
