Abstract
The rheological properties of polyethylene terephthalate melts containing a different amount of TiO2 were investigated within wide limits of stresses and shear rate gradients at 260–300°C. It was found that the anomaly of the viscosity properties of the melt increases with an increase in the concentration of TiO2. The apparent activation energy of viscous flow of PETP melts containing different amounts of TiO2 was estimated. The temperature dependence of the effective viscosity of the melts is intensified with an increase in the concentration of TiO2 in them.
