摘要
目前全世界聚四氢呋喃总产量已达到28万t/a,而我国产量很低,且产品质量不能满足生产需求,我国每年所需的1.5万t聚四氢呋喃主要依靠进口。因此应尽快开发和引进国际先进生产技术,以满足国内氨纶和聚氨酯弹性体的生产。
currently, the annual world polytetramethlene ether glycol output is nearly 0. 28 million tons. In China, the output and quality cannol meet the produce need,so it is necessary to develop and intro-duce advanced produce process to meet the market need.
