Abstract: The poly-r-(lysine) propylsiloxane supported palladium catalysts were synthesized andcharacterized. The catalysts showed a high activity for acrylonitrile hydrogenation whenthe molar ratio of N/Pd was 3.4. The hydrogenation of cyclopentadiene appeared to be atwo-stage process. The solvents have an obvious influence on the hydrogenation activity ofthe catalyst.

Key words: polymeric palladium catalyst, L-lysine, polysiloxane, hydrogenation, acrylonitrile, cyclopentadiene
