摘      要：正 In this study, corn stover was liquefied in acidic conditions, and several polymer materials were subsequently prepared from the liquefied mass. The effectual solvent for the liquefaction process was selected, and the influence of various liquefaction conditions was also investigated. The polyols from the liquefaction were then separated and purified through a series of processes, such as dilution, pH adjustment, filtration, evaporation and ozonolysis. Processes for
