Zusammenfassung:
Heterogenized representatives of neutral phosphine sulfonato Pd(II) complexes for polar monomer insertion polymerization were prepared by two different approaches. [{κ2-(P,O)-(2-anisyl)2PC6H4SO2O}Pd(Me)L] (L = pyr, dmso, or Cl) complexes were physisorbed on inorganic substrates, namely, clay or silica. In addition, new phosphine sulfonato complexes bearing hydroxyl linker groups at the nonchelating P-aryl moiety were prepared. These complexes were covalently tethered to cross-linked polystyrene. All immobilized palladium complexes are active in ethylene polymerization and
ethylene/MA copolymerization without any additional cocatalyst. In addition, separation from the polymer solution formed and reutilization for another polymerization were demonstrated for polystyrene-bound complexes.
