An equation of state proposed by Schotte was used to calculate vapor-liquid equilibria for ethylene + polyethlene (PE) system. The logarithmic distribution function was adopted to describe the molecular weight distribution of polyethylene and vapor-liquid calculations were at 403.15K for three number-average molecular weights M^^-_n' 2.16×10^4, 2.36×10^4 and 2.78×10^4. The calculated results show fairly good agreement with the experimental data shown in the literature. The difference among M^^-_n of feed PE gives no significant change in vapor-liquid equilibria and M^^-_n distributed in vapor phase though M^^-_n distributed in liquid phasedepends on M^^-_n of feed PE.
