Applications
THF can be polymerized by strong acids to give a linear polymer called poly(tetramethylene ether) glycol (PTMEG), CAS Registry Number, also known as PTMO, polytetramethylene oxide. The primary use of this polymer is to make elastomeric polyurethane fibers like Spandex.
THF is also a starting material for the preparation of tetrahydrothiophene using hydrogen sulfide over a heterogenous acid catalyst.
