Aromatic polyamides(PA) are widely used as a high-performance polymer in advanced technologies due to their outstanding thermal and mechanical characteristics. Nevertheless, PAs have a problem like poor solubility in most organic solvents leading to limitation on their application. To overcome this problem, many research efforts have been made to enhance its solubility by introducing bulky pendant groups or flexible linkage into polymer backbone. Ether linkage is easily considered as a flexible linkage and offers enhanced solubility, color, and melt-processing properties. In addition, incorporation of CF3 pendant group can also be considered as an effective means to improve the polymer solubility without deteriorating their properties. In this study, we designed unsymmetrical diamine monomer containing ether and CF3 groups as a linkage and pendant moieties, respectively, and synthesized a series of PAs from the monomer. These synthesis and characterization of the PAs will be presented.
