Rheological properties of PVA/Borax complexes in the presence of gelatin were investigated with shear stress(て) as a function of shear rate(r). PVA complexes showed pseudoplastic and 1.5―2.7 of die swell ratio. The apparent viscosity of this complexes were decreased in order to PVA/Borax > PVA/Borax/Gelatin> PVA/Borix Acid and first normal stress differance was increased with increased shear rate.
