Book excerpt: "This thesis uses theory and simulation to elucidate the fundamental principles and key mechanisms that govern demixing in compressible polyolefin solutions and its detection using acoustic wave propagation. Demixing by pressure-induced phase separation and its acoustic detection has direct applications to the industrial manufacturing of polyethylene based on the solution polymerization process, and is an evolving area of fundamental polymer thermodynamics.The two models developed, implemented and analyzed in this thesis for the structure and kinetics of pressure-induced phase separation in compressible polymer solutions and its acoustic detection, integrate total mass, component mass, momentum with the Sanchez-Lacombe equation of state, Newtonian and Maxwellian rheological equations and generalized the Fick's flux equations that include compressibility.
