Republic of China ## SYNOPSIS Poly(ether ether ketone ketone)-poly(ether sulfone) (PEEKK/PES) block copolymers were prepared from the corresponding oligomers via a nucleophilic aromatic substitution reaction, and the A?" of the PEEKK segment was fixed a t 12,000, while the M,,'s of the PES segmen
Poly(ether sulfone) and poly(ether sulfone ketone) copolymers (I-V) were synthesized by the nucleophilic substitution reaction of 4,4Ј-dihydroxy diphenyl sulfone (DHDPS, A) with various mole proportions 4,4Ј-difluoro benzophenone (DFBP, B) and 4,4Ј-difluoro diphenyl sulfone (DFDPS, C) using sulfolan
## Abstract 2,6‐Bis(β‐naphthoxy)benzonitrile (BNOBN) was synthesized by reaction of β‐naphthol with 2,6‐difluorobenzonitrile in __N__‐methyl‐2‐pyrrolidone (NMP) in the presence of KOH and K~2~CO~3~. Poly(ether ketone ether ketone ketone)(PEKEKK) /poly(ether ether ketone ketone) (PEEKK) copolymers c
## Abstract Structures of poly(ether ether ketone ketone)‐poly(ether biphenyl ether ketone ketone) copolymers were studied by using small angle X‐ray scattering and the one‐dimensional electron density correlation function method. The results revealed that structures of the aggregated state of the
