Solubility of ethylene in liquid, low‐density polyethylene to 69 atmospheres

Abstract
Ethylene solubility in low‐density polyethylene has been measured using the piezoelectric sorption method from 0 to 69 atm at 126, 140, and 155°C. The measured solubility data indicate lower ethylene solubility in polyethylene at a given temperature and pressure than a previously published extrapolation of infinite‐dilution results. The data are interpreted using the Flory–Huggins solution theory.
