摘要
A novel controllable cross\|linking PEEK was synthesized by introducing thioether moieties into PEEK rigid chain, in which sulfur acts as a cross\|linking point. It is found that the cross\|linking reaction could take place at 623 K over a period of 5 h. The novel material has an excellent thermal stability and mechanical properties. It can be processed as convenient as that of pure PEEK before cross\|linking and has a high application temperature as thermosetting resin after cross\|linking.
