TEMPERATURE-RESPONSIVE CATALYSTS

摘要

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-% of units derived from one or more non-functionalized monomeric units A, 0.1 wt-% - 50 wt-% of units derived from one or more functionalized monomeric units B, 0 wt-% - 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 (meth)acrylates and monomers co-polymerizable with (meth)acrylates, which contain one or more phosphorous and/or nitrogen containing uncharged electron donors as coordinative groups; and wherein cross-linking monomeric units C are selected from compounds which comprise at least two olefinically unsaturated double bonds co-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 of 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.
