Key words: crosslinked polystyrene, palladium compounds, supercritical carbon dioxide, composite, palladium particles, hydrogenation, diphenylacetylene, activity

By impregnation of super-crosslinked polystyrene with palladium compounds in the
medium of supercritical carbon dioxide (SC-CO₂) with their subsequent reduction
by molecular hydrogen, composites — particles of metallic palladium in the polymer
matrix were obtained. The synthesized composites exhibit high catalytic activity in the
liquid-phase hydrogenation of diphenylacylene, specific activity (TOF) is 15—50 min^-1,
selectivity in the hydrogenation of one triple bond is 60—80% at ~90 % conversion of
the substrate.
