A novel supported salenCrIIICl catalyst for alternating copolymerization of cyclohexene oxide with carbon dioxide

A novel heterogeneous catalyst was prepared by immobilizing salenCr III Cl on a modified poly (aniline-co-o-aminophenol) (MPOAP). The FT-IR, TEM, XRD, XPS and ICP results indicated that salenCr III Cl was successfully supported on MPOAP. The resulted catalyst (MPOAP-salenCr III Cl) exhibited excellent catalytic performance for alternating copolymerization of cyclohexene oxide (CHO) with carbon dioxide (CO 2 ). Moreover, the supported catalyst had an obvious effect on the microstructures of the copolymerization and the obtained polymer was found to be a linear alternating copolymer with narrower molecular weight distribution. The TG and DTG results indicated that the product prepared by the supported catalyst possessed higher decomposition temperature.
