Notes:
Several polyamides that contained cardo units were prepared. Thus 9,9-bis(4-aminophenyl)fluorene and 9,9-bis(4-aminophenyl)anthrone were condensed with 2,5-dimethyl-1,4-benzenediacetyl chloride, 2,4-dimethyl-1,4-benzendiacetyl chloride, and 2,5-dimethoxy-1,4-benzediacetyl chloride. Lowtemperature solution polycondensation in dimethyl acetamide (DMAc) was used throughout. The polymers were obtained in 80-90% yield and possessed intrinisic viscosities in the range of 0.6-1.2. The polymers were characterized by infrared (IR) spectra and elemental analysis. The solubility, crystallinity, and thermal stability of the polyamides were also determined.
