���Ѵ���(English) Catalytic hydroformylation and hydroxymethylation of unsaturated polymers is apost polymerization process to introduce reactive functionalized groups such asaldehyde groups or hydroxyl groups, onto backbone polymers. This reactive polymer canbe used for grafting, crosslinking or further modification reactions. Thehydroformylation of high molecular weight ~icis~i- 1,4-polybutadiene in the presence ofHn(CO)(PPh(,3))(,3) as catalyst and monochlorobenzene as solvent was studied. Thedegree of conversion was examined using ('1)H-NMR spectroscopy. From a 2('4) factorialexperimental design, temperature, catalyst concentration and total pressure appear tobe significant factors. A detailed kinetic study was carried out in a Parr batchreactor and a computer controlled batch reactor by monitoring the amount of synthesisgas consumed during the reaction time. The kinetic results indicate that thehydrofomylation is first order with respect to each of catalyst concentration, andcarbon-carbon double bond concentration and H(,2)/CO pressure (1:1 ratio) in thepressure range of 13.8 and 30 bar. Effects of CO concentration in synthesis gas,added triphenylphosphine, and stirring speed were also studied. Mechanistic aspectsof the catalytic process are discussed. Hydroxymethylation was achieved by subsequent hydrogenation of hydroformylated'polybutadiene using Ru(CH=CH(Ph))Cl(CO)(PCY(,3))(,2) under fairly severe conditions.The thermal properties of the hydroformylated and hydroxymethylated polybutadienewere characterized. The results show that the hydroformylation can increase theglass transition temperature of the polymer. However, the thermal stability ofhydroformylated and hydroxymethylated polybutadiene does not significantly change.
