A polyether diol poly[3 -bromomethyl-3 -tridecafluorooc-tyloxymethyloxetane]glycol ( PFBOX 3) was prepared in 91% yield from ring opening polymerization of 3 -bromomethyl-3 -tride-cafluorooctyloxymethyloxetane 2 which was derived from 3,3-di-bromomethyloxetane 1 and 1H, 1H, 2H, 2H-perfluorooctanol. The waterborne fluorinated polyurethane FPU was thus obtained by condensed polymerization of PFBOX 3 with isophoron-ediisocyanate (IPDI). The structure of FPU was characterized by Fourier transform infrared spectrometer ( FTIR). FPU showed good thermal stability under 300℃. The surface properties of FPU were studied by applied on cotton fabric. The treated fabric surface showed excellent water repellent property as the contact angle reached 147°. On the other hand, the surface showed slightly oil repellent property as the contact angle for nujol droplet was 126°.
