It was demonstrated that the catalyst system based on acacRh(CO)2 and polyorgano-siloxanes exhibits high activity and stability in hydroformylation of 1-hexene. The effects of the nature of the oligomer, the ratio of oligomers, and the oligomer: rhodium ratio in the polymer on the synthesis and catalytic properties of the system were studied.

The hydroformylation of olefins in the presence of catalytic systems based on RhCl3 and polymeric pyrrolidinopyridines was studied. lt was shown that the catalytic system has high activity in the hydroformylation of isobutylene under conditions when the activity of conventional homogeneous catalysts is low. The polymeric catalysts are also thermostable. The effect of solvents on the catalytic properties of the system was studied.

s The hydroformylation of olefins in presence catalytic systems on a basis RhCl3*3H2O and a copolymer of styrene with 4-N-pyrrolidinopyridine units in a main chain and acacRh(CO)2 and polymeric organosiloxanes was investigated. These catalytic systems have high stability and activity. The hydroformylation of isobutylene in the presence of such systems proceeds with high speed in conditions, when traditional homogeneous catalysts unactivity. It was showed by ESCA, that complexing of rhodium with pyrrolidinopyridine units of copolymer occurs on atom of nitrogen of pyridine ring. The influence of composition and structure of polymeric supports on creation of active centers of catalysts and their catalytic properties was investigated. The influence of solvents on catalytic properties of polymeric catalysts was studied.
