摘要
Enantioselective alternating copolymerizaion from carbon monoxide and styrene was carried out using cationic palladium catalyst modified by 1, 4-3, 6-dianhydro-2, 5-O-bis（benzo[1,3,2]dioxaphospholyl-2）-D-mannitol.The chiral diphosphine was proved to be effective in the enantioselective copolymerization. The pure poly（1,4-ketone）were obtained and characterized by GPC,（）1H-NMR,（）13C-NMR,IR and elemental analyzer.
