Preparing method of poly (carbonic ester-ether) polyalcohol
ActiveCN102617844AIncreased content of carbonate unitsSuppression of continuous insertionCyanidePolyol
The invention discloses a preparing method of poly (carbonic ester-ether) polyalcohol. Rare-earth doped bi-metal cyanides based on Zn3[Co(CN)6]2 serve as catalysts, carboxylic acids serve as chain transfer agents, and carbon dioxide and epoxy compounds are performed with a copolymerization reaction to obtain the poly (carbonic ester-ether) polyalcohol. Compared with the prior art, the carboxylic acids serve as chain transfer agents, and due to the fact that the carboxylic acids are strong in coordination capability, faster in chain transfer, capable of restraining continuous inserting of epoxy monomers and free of ether structure, unit content of carbonic ester is improved, and the prepared poly (carbonic ester-ether) polyalcohol has higher carbonic ester unit content. Experimental results indicate that molecular weight of the prepared poly (carbonic ester-ether) polyalcohol is 1500g / mol-5000g / mol, molecular weight distribution is 1.11-1.50, unit content of the carbonic ester is 40%-80%, catalytic activity is larger than 1.0kg / gLn-DMC, and cyclic carbonic ester content is less than 10wt%.
