The solubility of ethylene in toluene and in toluene (90 wt %)/styrene–butadiene rubber (SBR; 10 wt %) solutions was determined because the solubility data were of interest for the kinetic study of the metallocene‐catalyzed homopolymerization of ethylene and the copolymerization of ethylene with α‐olefins. The data were obtained over the temperature range of 293–343 K and the pressure range of 50–180 psi. An original Universal Functional Group Activity Coefficient (UNIFAC) model was applied for the ethylene–toluene system, and a UNIFAC‐ZM model (a modified UNIFAC model proposed by Zhong and Masuoka et al.) was applied for the ethylene–toluene/SBR ternary system. Henry's law was also used to correlate the experimental results of the two systems. A comparison was made between the UNIFAC models and Henry's law. © 2005 Wiley Periodicals, Inc.
