Process for the hydroformylation of olefinically unsaturated polymers in aqueous dispersion

摘要

A process for the hydroformylation of polymers containing ethylenic double bonds (I) by reacting (I) with carbon monoxide (CO) in presence of a hydroformylation catalyst, the reaction being carried out in an aqueous dispersion of (I) under conditions such that the catalyst is at least partly in the polymer phase or at least partly in the polymer/water interface. Also claimed are (i) polymer dispersions obtained by this process and (ii) polymers obtained from these dispersions by removing the aqueous solvent.
