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. 在管式反应器中聚合环氧烷烃。通过沿所述管式反应器长度定位的多个引入点将所述环氧烷烃连续引入所述管式反应器中。单体流速沿所述反应器的长度增加，以保持几乎恒定的未反应的环氧烷烃的浓度。
