Synthesis and properties of poly(aryletherether ketone) and its` variants
- Jilin Univ., Changchun (China)
Poly(ether-etherketone) (PEEK) and its variants were prepared by a nucleophilic aromatic substitution reaction. The inherent Viscosity of polymers can be controlled by adjusting the molar radio of monomers. In the synthesis, we found that the end-group choosing are very effected on the thermal stability of the polymers. Various properties of these polymers were investigated by TGA, DSC, and Wide-Angle X-ray. In this paper, we also reported a promising approaches toward reducing of processing temperature and crystallization rate by using a diphenol group involved PEEK copolymer, modifying of the glass temperature and melting point by the molar ratio of ether/ketone groups, verifying the crystallization rate and crystallinity by the substitution of para-phenyl for meta-phenyl in the PEEK main chain, and optimizing the morphology and mechanical properties by polymerization of poly(arylether-ether-ketone) and its` variants.
