Polytetrahydrofuran, also called poly(tetramethylene ether) glycol or poly(tetramethylene oxide), is a chemical compound with formula (C4H8O)nOH2 or HO-(-(CH2)4O-)n-H. It can be viewed as a polymer of tetrahydrofuran, or as the polyether derived from 1,4-butanediol.
Polytetrahydrofuran is commonly prepared by acid-catalyzed polymerization of tetrahydrofuran. The starting material is natural gas, which is converted to acetylene, then reacted with formaldehyde to make butynediol and then butanediol. The latter is turned into tetrahydrofuran by action of a catalyst and then polymerized.
Polytetrahydrofuran is widely used to produce thermoplastic polyyrethane (TPU), spandex, Copolyester – ethers (COPEs) and others.

The demand of global polytetrahydrofuran was about 0.8 million tons in 2014, and is expected to reach 1.1 million tons by 2019, growing at a CAGR of 6.0% from 2015 to 2019. In terms of consumption, the consumption of three countries (including USA, Europe and Japan) accounts for about 90% of total world consumption. Due to the different levels of development of various countries and regions, its consumption growth is different. Development of the United States polytetrahydrofuran was earlier; the development of polytetrahydrofuran in Western Europe has been rapid; spandex fibers are the largest consumption field of polytetrahydrofuran in Japan; since few large companies abroad has been monopoly on polytetrahydrofuran technology, so research and development of Chinese polytetrahydrofuran is late, severely restricted the development of production of downstream products spandex.
