For the first time the treatment of polystyrene in sub- and supercritical freon media
in comparison with supercritical carbon dioxide was studied. Subcritical freon R22
can more efficiently saturate polystyrene than subcritical freon R410а and supercritical
freon R23 and carbon dioxide. The subsequent heating of polystyrene samples saturated
with R22 freon leads to the formation of the polymer with connected porous structure
and average pore size up to 250 μm. The results obtained can be used in the development
of technologies for porous polystyrene production.
