Pressure effects in the capillary flow of newtonian and shear-thinning polymers.

Abstract
Chapter I and Appendix A introduce the problem of a viscosity increase with increasing shear rate. The phenomenon is related to possible shifts in the glass transition, Tg. The WLF and Tammann-Hesse equations are used to correlate viscosity changes with shifts in Tg. The initial parameters considered which possibly affect Tg are frequency, shear rate and pressure.
