Shear viscosity of polyphenylsulfone melt was determined using capillary rheometer. Temperature and pressure dependencies of shear viscosity were recorded via measurements in temperature and pressure regions covering regular processing conditions of polyphenylsulfone. Obtained flow curves were fitted by the help of the Carreau-Yasuda model. Temperature and pressure effects on viscosity behaviour were evaluated through temperature, α, and pressure, α , sensitivity coefficients.
