Bio-based polyamides with high transparency and low yellowness were synthesized using 4,4-bis(trifluoroacetamido)--truxillic acid (ATA-F1) and 4,4-bis(pentafluoropropionamido)--truxillic acid (ATA-F2) as a fluoroalkylated aromatic dicarboxylic acid, and various aromatic diamines. The introduction of fluorine side chains improved the transparency of the polyamide film, and suppressed its yellowness. On the other hand, water repellency, which should be a general characteristic of the fluorinated polymers, was not observed. By using ATA-F1 and various aromatic diamines, aromatic and fluorinated polyamides were obtained. In addition, these also demonstrated a high transparency and a low yellowness index. The heat resistance properties of all the obtained polyamides was over 250 degrees C, and the characteristics of the bio-based polyamides from 4-aminocinnamic acid derivatives were retained.
