摘要

研究表明，基于含金刚烷的二胺和 2,3,3′,4′-联苯四羧酸二酐（a-BPDA）和 5,5′-(1,1,1,3,3,3-六氟丙烷-2,2-二基)双(2-苯并呋喃-1、3-二酮）（6FDA）具有良好的热氧化性能（T5% = 465-485 °C）和较高的光学透明度（T400 = 60-80%），而基于相同二酐和 2,2′-双（三氟甲基）联苯-4,4′-二胺（TFBA）的共聚亚胺则含有笨重的三氟甲基片段（T400 = 38-67%）。

Synthesis of optically transparent copolyimides based on alicyclic and fluorine-containing diamine

It was shown that copolyimides based on adamantane-containing diamine and dianhydrides of 2,3,3′,4′-biphenyltetracarboxylic acid (a-BPDA) and 5,5′-(1,1,1,3,3,3-hexafluoropropane-2,2-diyl)bis(2-benzofuran-1,3-dione) (6FDA) are characterized by good thermal-oxidative properties (T_5% = 465–485 °C) and a high optical transparency (T₄₀₀ = 60–80%) in comparison with copolyimides based on the same dianhydrides and 2,2′-bis(trifluoromethyl)biphenyl-4,4′-diamine (TFBA), containing bulky trifluoromethyl fragments (T₄₀₀ = 38–67%).
