摘　　要：A novel cross-linkable poly(ether ether ketone ketone) alternating copolymer was synthesized by introducing thio-ether moiety to PEEKK rigid main chain. The copolymer can be processed at 628 K and be cross-linked by annealing at 653 K for 5 h. The cross-linking reaction was caused by the introduced thio-ether moiety instead of the PEEKK moiety. The cross-linked material has better mechanical properties and thermal stability that uncross-liked one. The results will give proof to the further research on controllable cross-linking PEEKK. This material is anticipated to be processed as a thermoplastic material as well as used a as thermosetting material after being cross-linked.
