Abstract
Fluid-liquid pressures are measured and correlated with two SAFT equations of state for poly(ethylene-co-octene-1) solutions in supercritical ethylene at temperatures up to 180 degreesC. These cloud-point pressures are found to depend strongly on the molecular weight of the polymer and the branch de nsity but weakly on the polymer concentration in the range from 0.05 to 0.1 5 polymer weight fraction. EO solutions in ethylene are found to exhibit U- LCST behavior.
