ABSTRACT:
Polymers containing ethylenically unsaturated double bonds are hydroformylated by reacting aqueous dispersions of the polymers with hydrogen and carbon monoxide in the presence of suitable hydroformylation catalysts.
Also provided are the polymer dispersions obtainable by this process and the hydroformylated polymers themselves.
