Abstract
The novel Pt-and Rh-containing polymers based on polystyrene-polybutad iene block copolymers were studied in hydrosilylation of three systems of reagents: styrene/triethylsilane, 1-hexene/dimethylchlorosilane, a nd cyclohexanone/triethylsilane. All polymers containing Pt and Rh com plexes were found to display some catalytic effect whose effectiveness for the same system of reagents is dependent on the nature of the pol ymeric ligand. On the other hand, the reagent nature influences even m ore strongly the catalytic properties of polymers. No side products of hydrosilylation was observed with Rh-containing polymer catalysts in cyclohexanone/triethylsilane system.
