General description

Poly(tetrahydrofuran) (PTHF) is a highly flexible hydrophobic polymer widely used in the synthesis of thermoplastic elastomers such as polyesters and polyurethanes. The addition of PHTF imparts abrasion resistance, hydrolytic stability, and attractive dynamic properties to the material. This polymer can also be used to prepare block copolymers, end-functional star polymers, amphiphilic conetworks, and thermogels.

Application

Poly(tetrahydrofuran) can be used as a precursor to synthesize epoxy-urethane polymer networks. It can also be used as a diol comonomer to synthesize block copolymers, such as poly-(alkyleneterephthalаte-co-alkylenephosphate).
