Samples of virgin and a crosslinked fluorinated rubber, containing different amounts of carbon black and solvated with methylethyl ketone, have been investigated by differential scanning calorimetry. Although the polymer–solvent interaction increases with decreasing temperature, a process of solvent separation was observed for all of the systems. This process can be attributed to a T g regulation effect in which solvent crystallization occurs only when the crystallization temperature is higher than the T g of the system. The interaction between rubber and filler, approximately temperature independent, was found to not influence the glass transition of the rubber–methylethyl ketone systems, even when the carbon black content is on the order of 35 wt %. © 1999 John Wiley & Sons, Inc.
