Ring-opening polymerization of ethylene carbonate to improve the liquefaction of corn stalk

Ring-opening polymerization of the ethylene carbonate was conducted to obtain poly ethylene carbonate, which was used to liquefy the corn stalk other than ethylene carbonate(EC). It was found that the yield of the liquefaction was 31.4% higher that by using EC. The FTIR(Foarier Transform Infrared Spectroscopy) spectra of the liquefied corn stalk showed that the carbonate units were successfully transferred into the new production. As a result, the carbonate product which was biodegradable can make the liquefied production based polyurethane environment-friendly material.
