The relative importance of the higher solubility of n ‐hexane (with respect to ethylene) and its associated heat of sorption on the thermal behavior of the growing polymer particles during gas phase ethylene polymerization on supported catalysts are investigated. It is found that if a polymerizing particle begins to heat‐up, the partial desorption of a condensable solute in a gaseous state helps to attenuate the temperature rise in the polymer particles, decreasing the risk of local hot spots.
