## Abstract Poly(ether ether ketone) (PEEK)/poly(ether sulfone) (PES) block copolymers were synthesized via condensation reaction between fluorineβterminated PEEK oligomers and hydroxylβterminated PES oligomers. The dynamic mechanical behavior of a composite sample prepared by compression molding o
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(pheny1ene sulfide)-poly(ether sulfone) (PPS-PES) block copolymers were synthesized by polycondensation of chloro-terminated PPS oligomers and hydroxylic-terminated PES oligomers at atmospheric pressure. The structure and compositions of PPS-PES block copolymers were analyzed quantitatively by F
