Synthesis of newly functional polyols by ring-opening polymerization of ethylene oxide and propylene oxide catalyzed by double metal cyanide catalysts |
초록 |
A series of double metal cyanide (DMC) catalyzed ring-opening polymerization of propylene oxide (PO) and PO / ethylene oxide (EO) were demonstrated. The DMC catalysts prepared by ZnCl2 and K3[Co(CN)6]2 in the presence of various organic complexing agents together with polymeric co-complexing agents exhibited excellent catalytic activity in the reaction. The microstructure of obtained polyols are well analyzed by NMR spectroscopy, gel permeation chromatography and viscometry. The unsaturation level and OH value of such polyols were also measured by titrator. |
