新型含硼聚芳醚酮的制备、性能及在偶氮聚芳醚酮合成中的应用
Synthesis and Properties of a Novel Boron-containing Poly(aryl ether ketone) and Its Application in the Preparation of Azo Poly(aryl ether ketone)
摘要
Abstract
Novel poly( aryl ether ketone) s with pendant pinacolboronate groups( PAEK-Bpin) and boric acid groups(PAEK-BOH) were synthesized. PAEK-Bpin was prepared by the borylation of poly(aryl ether ketone) in the presence of [ IrCl( COD) ] 2 and dtbpy. The quantitative introduction of borate can be controlled by the amount of Bis( pinacolato) diboron( B2 pin2 ) . PAEK-BOH was obtained under the action of NaIO4 . Azo-PAEK was obtained via Suzuki-Miyaura reaction. The structure and property characterizations of all related products were carried out using 1 H-nuclear magnetic resonance ( 1 H NMR ) , ultraviolet and visible spectrophotometer (UV-Vis), gel permeation chromatography(GPC), differential scanning calorimetry(DSC) and thermogravi-metric analysis( TGA) . The results of structure characterization suggest that products are synthesized. The re-sults of GPC show that Ir catalyst and Suzuki-Miyaura reaction do not affect the molecular weight of the poly-mers. DSC results indicate that the glass transition temperature of PAEK-Bpin increases with the increase of the amount of boronate. However, PAEK-Bpin has good solubility in most of polar aprotic solvents. The prep-aration of boron-containing poly( aryl ether ketone) provides more broad prospects for further functionalization of the poly( aryl ether ketone) .关键词
