This paper was concerned with synthesis of poly-y-(L-tryptophan) propylsiloxane palladium complex catalysts in different -COOH/Pd ratio. The data indicated that the hydrogenation activity of the title catalyst was very high. Initial rate of styrene hydrogenation was 4972 mlH2/min. mmol Pd when the -COOH/Pd
mol ratio 4.5:1. Besides
the hydrogenation activity increased with the increasing of the -COOH/Pd mol ratio. The influence of polar solvent was higher than nonpolar solvent.
