摘要
A novel controllable cross-linking PEEK was synthesized by introducing thioether moieties into PEEK rigid chain, which was combined with merits of thermoplastic material and thermosetting material because it can be processed as a thermoplastic material before cross-linking and be applied as a thermosetting material after being crosslinked by electron beam and heat cross-linking reaction. In this paper, we mainly discussed the rheological behavior of controllable cross-linking PEEK at a dynamic time and 653 K. The variation of modulus and complex viscosity and rheological regularity of the materials with different molecular weights were investigated by tracking and monitoring process of cross-linking reaction using retary rheometer. The relationship between structures and properties of controllable cross-linking PEEK was explored.
