DOI: 10.5755/j01.ms.26.3.22302
Abstract: Epoxycyclohexane-epichlorohydrin polyether polyol was synthesized by using epoxy cyclohexane and epichlorohydrin as raw materials, glycerol as an initiator, dichloromethane as solvent and aluminum chloride as catalysis. The structure of the copolyether was characterized by infrared… read more here.
