摘　　要： A series of polymer-supported tetranuclear rhodium carbonyl cluster catalysts were prepared b the reaction of Rh4（CO）12with several kinds of polymer supports such as crosslinked poly （N-vinylpyrrolidone） （PNVP） and crosslinked poly （ styrene-co-maleic anhydride） （PMAn）, and subsequently were used to catalyze the hydroformylation of olefins. The catalysts were characterized by IR, SEM and XPS. The influence of the supports structure and crosslinking, metal’s content and particle size of the supports on the catalysts hydroformylation properties was studied. The factors which affect the catalytic conversion were also examined. The experimental results show that the polymer-supported Rh cluster catalysts possess very high catalytic activity and aldehyde selectivity as well as good reproducibility.<正> A series of polymer-supported tetranuclear rhodium carbonyl cluster catalysts were prepared b the reaction of Rh4（CO）12with several kinds of polymer supports such as crosslinked poly （N-vinylpyrrolidone） （PNVP） and crosslinked poly （ styrene-co-maleic anhydride） （PMAn）, and subsequently were used to catalyze the hydroformylation of olefins.
