1′-diol and hydroquinone via polycondensation.The technique of 13C-NMR was employed to determine the content of the two bisphenols in the copolyetherketones.The chain structure was characterized by illustrating the average block length (LA
LD) in terms of the portion of different triads (AKA
DKD
AKD).The synthesized copolyetherketones have the properties of excellent solubility
high heat-resistance
goodtensile strength and good selectivity for gas permeability.
