摘要：

Citraconic end-capped amide-imide precursor has been synthesised by reaction of methylene-bis-[N-(4-phenylene)-4′-(chloroformyl)phthalimide] with 4,4′-diaminodiphenylmethane and citraconic anhydride followed by chemical imidisation. Thermal polymerization of this precursor at 240°C led to crosslinked polyamide-imide. This polymer is thermally stable up to 400°C, i.e. higher than the corresponding temperature for crosslinked polyimide obtained by thermal polymerization of N,N′-biscitraconimido-4,4′-diphenylmethane. © 1990.
