Phase Equilibria of Dilute Poly(ethylene-co-1-butene) Solutions in Ethylene, 1-Butene, and 1-Butene + Ethylene

Fluid−liquid and solid−fluid transitions were measured for dilute poly(ethylene- co -1-butene) solutions in ethylene, 1-butene, and ethylene + 1-butene from about −50 °C to about 180 °C and up to 1500 bar. The experimental fluid−liquid data were correlated with a copolymer SAFT equation of state.
