Synthesis, characterization and properties of TAP-6FDA hyperbranched polyimides with different branching degrees 作者:Chen, Y (Chen, Ying)[ 1 ] ; Zhang, QY (Zhang, Qiuyu)[ 1 ] ; Sun, WL (Sun, Wanlu)[ 1 ] ; Lei, XF (Lei, Xingfeng)[ 1 ] ; Yao, P (Yao, Pan)[ 1 ] POLYMER INTERNATIONAL 卷: 63 期: 4 页: 788-795 DOI: 10.1002/pi.4594 出版年: APR 2014 查看期刊信息 POLYMER INTERNATIONAL 出版商 WILEY-BLACKWELL, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA ISSN: 0959-8103 eISSN: 1097-0126 研究领域 Polymer Science 摘要 A series of hyperbranched polyimides were successfully synthesized by condensation polymerization of A(2)-type dianhydride monomer 2,2-bis(3,4-dicarboxylphenyl) hexafluoropropane dianhydride (6FDA) and B ' B-2-type triamine monomer 2,4,6-triaminopyrimidine (TAP). Polymers with different branching degrees (DB) and terminated groups were obtained by changing the monomer addition order and the monomer molar ratio. Fourier transform infrared spectroscopy and H-1 NMR were used to verify the structure of the prepared polyimides, which indicated that the amino group still existed in all the products. The DB of the polymers indicated by H-1 NMR increased from 30% to 79% with the molar ratio of TAP:6FDA decreasing from 1:1 to 1:2. The absolute molecular weights were measured by size-exclusion chromatography with multi-angle laser light-scattering detection, which suggested that the highest molecular weight would be obtained when the molar ratio of amino groups:anhydride groups of the monomers was 3:3.2. With the DB increasing, the d-spacing values indicated by wide angle X-ray diffraction increased from 5.15 angstrom to 5.68 angstrom and the UV - visible spectra of the polymers exhibited decreasing cut-off wavelengths. The 5% weight loss temperature in nitrogen increased with decreasing content of TAP monomer, and the glass transition temperatures of the obtained polyimides decreased from 282 degrees C to 258 degrees C with increasing DB.
