General description

Poly(tetrahydrofuran) (PTHF) is a polyether that can be prepared by the cationic polymerization of tetrahydrofuran in the presence of a variety of initiator systems.[1]

Application

PTHF can be used in the preparation of soft segment polyurethane for a variety of applications.[2][3] It can also be used in the surface modification of cellulose fibers which can further be used as reinforcing polymerix materials.[4]
