In this work, carbon monoxide (GO) and 4-vinylcyclohexene (VCH) with [Pd(CH3CN)(4)](BF4)(2) were copolymerized under various conditions at 60 degrees C. Elemental analysis and infrared, UV, and NMR spectra indicated that copolymers containing a ketone and a cyclic structure of cyclohexyl and norbornane groups are produced. Bidentate nitrogen ligands proved to be more effective at stabilizing catalytic activity than monodentate phosphorus or nitrogen ligands. Also, the bulk substituent on the bidentate ligand led to inactive catalysts. Methanol served as the coinitiator and chain transfer agent. Increasing the concentration of 4-vinylcyclohexene caused the copolymer’s CO content to be enhanced. TGA revealed that the copolymer’s mass loss starts at 120 degrees C and the maximum peak of decomposition occurs at 450 degrees C. Moreover, X-ray diffraction analysis demonstrated the copolymer to be partially crystalline. Furthermore, reduction of 4-vinylcyclohexene/CO copolymer with LiAlH4 in THF yields a hydroxyl-containing polymer.
