Notes:
New pseudo dibenzoylphthaloyl chlorides, namely, 2,5-dibenzoylterephthaloyl, 4,6-dibenzoylisophthaloyl, and 4,6-di(p-toluyl)isophthaloyl chlorides, were synthesized as monomers. The ring-opening polyaddition reaction of the pseudo dibenzoylphthaloyl chlorides with aliphatic diamines in N-methyl-2-pyrrolidone afforded a new class of polyamides having inherent viscosities of 0.2 ∼ 0.6 in quantitative yield. The solution polymerization was almost completed within 30 min at room temperature. All of the polyamides were soluble in a wide range of solvents including tetrahydrofuran. These polymers began to decompose at around 300°C both in air and under nitrogen as determined by differential thermal analysis (DTA) and thermogravimetric analysis (TGA).
