摘要：

Pd++ catalysts with bis(diphenylphosphino)alkane ligand and methanol as coinitiator were found to be very active for the alternating copolymerization of carbon monoxide with propylene, butene-1 and hexene-1. The catalysts with bis(diphenylphosphino) propane and butane have the highest polymerization activities but only modest regiospecificity. The chiral (-)-2,3-0-isopropylidene-2,3-dihydroxy-1,4-bis(diphenylphosphino)butane-Pd catalyst has good activity as well as regioselectivity to produce semi-crystalline CO/propylene alternating copolymer.
