| abstract |
The present invention relates to a catalyst comprising (a) a polymer, which has a weight-average molecular weight in the range of from 1000 g/mol –100000 g/mol and which polymer comprises 50 wt-% -99.9 wt-% ofunits derived from one or more non-functionalized monomeric units A, 0.1 wt-% -50 wt-% of units derived from one or more monomeric units B, 0wt-% - 30 wt-% of units derived from one or more cross-linking monomeric units C; wherein monomeric units A are selected from (meth) acrylates and monomers co-polymerizable with (meth) acrylates; wherein monomeric units B are selected from hydroxyl-functionalized (meth) acrylates and monomers copolymerizable with (meth) acrylates,which are esterified with one or more suitable precursors of phosphorousand/or nitrogen containing uncharged electron donors as coordinative groups; and wherein cross-linking monomeric units C are selected from compounds which compriseat least two olefinically unsaturated double bondsco-polymerizable with A and/or B, and (b) a catalytically-active metal compound that is bound to one or more phosphorous and/or nitrogen containing uncharged electron donors of said polymer. Furthermore, the invention relates to corresponding polymers to afore-mentioned catalyst, a process for producing the catalyst and the polymer as well as the use of the catalyst in homogeneous and/or heterogeneous catalysis. |
