摘要
比较了低不饱和度聚醚多元醇与传统碱催化聚醚的多元醇性能和精制处理方法。详细介绍了双金属氰化物(DMC)配位催化聚醚多元醇的精制提纯技术进展,并总结了它们的优缺点。
Properties and Purification methods are compared between polyether polypls catalyzed by DMC or MMC and traditional ones catalyzed by KOH. The development of product purification tech-nologies is introduced in detail. The advantages and disadvantages of said technologies are summa-rized.
