A number of linear and crosslinked polymer ligands containing P or N or S as coordinative atoms were prepared. The hydroformylation of olefins was carried out at mild conditions in the presence of complexes as catalysts which were made by complexation reactions of these ligands with various homogeneous complexes or metal salts. The obtained results were explained in terms of the influences of the polymer matrix, or the structures and compositions of the polymer chain, and the properties of polymer‐metal complexes on activity and selectivity. The most important factor for enhancing the selectivity towards linear aldehyde lies in the properties of the polymer‐metal complex. High selectivity up to 95% was obtained by using polymer phosphine ligand‐Pt‐Sn complexes as catalyst in the hydroformylation of olefins. The hydroformylation mechanisms were discussed.
