Abstract

Hydroformylation reactions are carried out in the presence of a catalyst comprising a solid polymer of a trivalent phosphorus-containing compound having associated therewith a metal of the group cobalt, rhodium, ruthenium, platinum and palladium. The polymer, which can be formed in part of a polyvinylaromatic compound, can be used to remove catalyst residues from hydroformylation reaction effluent streams. p-styryldiethylphosphine and polymers thereof are disclosed.
