A new set of four fluorinated aromatic poly(benzamide imide)s was synthesized with the objective of preparing condensation polymers with good processability while maintaining high chemical resistance, thermal stability and good mechanical properties. Their synthesis was carried out using commercially available cycloalkane substituted diamines, 3,5-dinitrbenzoyl chloride and 4,4'-(hexafluoroisopropylidene)diphthalic
合成了一组新的四种氟化芳族聚(苯甲酰胺酰亚胺),其目的是制备具有良好可加工性同时保持高耐化学性,热稳定性和良好机械性能的缩聚物。使用可商购的环烷烃取代的二胺,3,5-二苯甲酰氯和4,4'-(六氟异亚丙基)二邻苯二甲酸酐(6FDA)作为起始原料进行合成。该研究集中在侧基的影响和计算方法的测试上,该计算方法可帮助根据其结构和可用的QSPR模型预测聚合物性能。为此,对这些新的聚酰亚胺进行了广泛的测试,包括IR,NMR,X射线衍射,UV吸收,热稳定性,机械测试,气体渗透和溶解度分析。结果表明,所获得的材料具有与许多市售聚酰亚胺相似的性能。另一方面,计算仿真表明,所采用的策略可能有助于减少要合成的化合物的数量,同时最大程度地提高找到具有某些所需特性的聚合物的成功率。
