| Abstract: | Hydroxyl-terminated novel polyether polyols were synthesized by polymerization of epichlorohydrin (ECH) catalyzed by double metal cyanide (DMC) catalyst. The effects of reaction temperature and catalyst concentration on the polymerization of Polyether Polyol were studied. The molecular structure and the damping properties were measured by IR spectra, 1H-NMR spectra and the dynamic mechanical analysis. |
