Process for selective hydrogenation of ethylenically unsaturated double bonds in p polymers, aqueous polymeric dispersion, and, polymer

摘要

'' PROCESS FOR SELECTIVE HYDROGENATION OF DOUBLE LINKS ETHYLENICALLY UNSATURATED IN POLYMERS P, E, WATER POLYMERIC DISPERSION ''. The invention relates to a process for selective hydrogenation of unsaturated ethylene double bonds in polymerisers (P), whereby the polymerisers (P) are reacted with hydrogen in the presence of at least one hydrogenation catalyst, said catalyst being selected from complex rhodium and / or ruthenium salts and compounds, in an aqueous dispersion of polymerisers (P) that contain no more than 20 percent by volume of organic solvent. The invention also relates to hydrogenated polymerisation dispersions obtained according to the inventive process, and to polymerisers obtained from said polymerisate dispersions. In addition, the invention also relates to aqueous polymerisate dispersions containing polymers (P ') which have the structural elements (I), (II) and (III) according to claim 10 and have optional structural elements (IV) and / or (V) according to claim 9.
