PROBLEM TO BE SOLVED: To enable hydroformylating a polymer in the state of an aqueous dispersion by using a specific catalyst under specific conditions. SOLUTION: This method for hydroformylating an ethylenic unsaturated polymer comprises reacting (C) carbon monoxide and (D) hydrogen with (B) the aqueous dispersion of a polymer having ethylenic unsaturated double bonds in the presence of (A) a hydroformylation catalyst under a condition that the catalyst is at least partially impregnated into the phase of the polymer or at least into the boundary of the polymer/aqueous phase. The component A is preferably the salt or complex of cobalt, rhodium or ruthenium, especially rhodium. The reaction conditions are preferably selected from a temperature range of 50-150 deg.C and a pressure range of 20-300 bars. The polymer dispersion preferably contains a (co)polymer produced from 10-100wt.% of at least one conjugated diene and 0-90wt.% of at least one monoolefinic unsaturated monomer capable of copolymerizable with the diene. |
