摘要：

High molecular weight alternating copolymers of propylene and carbon monoxide were prepared using a cationic palladium complex modified with 1,3-bis(di-n-butylphosphino)propane. Solid-state C-13 NMR analysis showed the presence of unexpected ketal repeat units in the isolated polymers which upon heating or dissolution in hexafluoro-2-propanol were converted into ketones. A mechanism involving intramolecular polymerization of ketone and depolymerization of poly(spiroketal) is proposed to account for the observations.
