Synthesis and Characterization of Poly(aryl ether ketone)s Containing Silican

Abstract

Abstract: The introduction of silane into the polymer backbone improves the solubility of the polymer without having a great influence on the thermal stability of the polymer. Therefore, the changes on the main-chain of PAEK were made to gain novel materials containing silane and all the polymers were prepared by low temperature polycondensation method. The glass transition temperatures were evaluated by differential scanning calorimetry(DSC) and the thermal properties were tested by thermal gravimetric analysis(TGA) which showed no mass loss below 350 ℃ in both air and nitrogen atmospheres. All the polymers were completely soluble in organic solvents such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-2-pyrrolidone, dimethyl sulphoxide(DMSO), and concentrated sulfonated acid(H₂SO₄^-). All these PAEK materials containing silane, which show excellent properties, were expected to be applied in composition or function material system.
