The organic polymer-supported catalysts were prepared by refluxing the mixture of poly(heterocyclic ether-ketone) (PEK), phenophthalein poly(ether sulfone) (PES-C), and two kinds of polyimides (PCK and PIK) with coordinating atoms (N, O) in their functional chains and PdCl~2 in ethanol/benzene, respectively. The carbonylation of allyl bromide and hydrogenation of 1-octene were carried out under atmospheric pressure and at 40℃. Among these catalysts, Pd-PEK(Ⅰ) (Pd wt%=0.22%) and Pd-PES-C(Ⅱ)(Pd wt%=0.28%) showed high catalytic activity to the carbonylation and hydrogenation. In particular, the catalysts Pd-PES-C with very low Pd content (0.04～0.05 wt%) also exhibited very high activity (TOF~m~a~x, 345mol CO/mol Pd·min and 493mol H~2/mol Pd·min). The influences of the preparation methods for the catalysts, the swelling effect and the functional chains of the polymers on the catalyst activities were also discussed.
