| 제목 | Catalyst Development for CO2/Epoxide and Ethylene/α-Olefin Copolymerizations: From Flask to Industrial Process |
| 초록 | A highly active catalyst was discovered for the CO2/propylene oxide (PO) copolymerization.It is a cobalt(III) complex prepared from a Salen-type ligand tethered by four quaternary ammonium salts (1). Complex 1 showed a high TON up to 16000 and a high turnover frequency (TOF) of 16000h-1 that produced a strictly alternating copolymer with a high molecular weight (Mn) of up to 300000. These performances of 1 allow for constructing a pilot plant for continuous commercial process. We developed a synthetic route for o-phenylene-bridged (tetramethylcyclopentadienyl, indenyl, or fluorenyl)/amido titanium complexes. The complexes can be prepared in two steps in Kg-scale(eq. 1). Higher activity, higher α-olefin incorporation, and higher molecular weight than the Dow-CGC ([Me2Si(η5-Me4C5)(NtBu)]TiCl2) are achieved. These features enable the complex to be applicable in a commercial process. |
