On the Effect of Pressure on the Shear and Elongational Viscosities of Polymer Melts
Original language description
The effect of pressure and temperature on the shear and elongational deformation rate dependent viscosities has been experimentally investigated for several polymers (HDPE, LDPE, LLDPE, PP, PC, PMMA, and PS) on a capillary rheometer with a backpressure device. Pressure and temperature, coefficients have been determined through simultaneous fitting of the shear and extensional viscosity data by the modified White-Metzner model. The dependence of and on temperature and pressure, respectively, was investigated and it has been found that simple relationships exist between pressure and temperature sensitivity coefficients for individual polymers.

Czech description
V této práci byl studován vliv tlaku a teploty na smykovou a elongační viskozitu pro následující polymery: HDPE, LDPE, LLDPE, PP, PC, PMMA a PS. Za tímto účelem byl modifikován výtlačný kapilární reometr a tlakové koeficienty byly stanoveny pomocí modifikovaného White-Metznerova modelu.
