Abstract
Alkylene oxides are polymerized in a tubular reactor. The alkylene oxide is continuously introduced into the tubular reactor through multiple introduction points located along the length of the tubular reactor. Monomer flow rates are increased along the length of the reactor to maintain a nearly constant concentration of unreacted alkylene oxide.
