Freezing processes of benzene in the presence of styrene-divinylbenzene gel beads were investigated by proton nuclear magnetic resonance spectroscopy. Some portion of benzene in the pore did not freeze below its freezing point, which was detected until -80 degrees C. Temperature dependence of the amount of unfrozen benzene was discussed in relation to the pore size and the cross-linking density of gel beads. The small pore size and high crosslinking density increased the amount of unfrozen benzene, whereas the polymer matrix concentration showed little effect on the freezing processes.
