Notes:
para-Phenylenediamine sulfate polymerized with 1,4-bis(trichloromethyl)benzene in SO3 at 〉 20% polymer concentration to form highly anisotropic (liquid crystalline) sulfonated poly(para-phenyleneterephthalamide) (S-PPT) solutions with inherent viscosities as high as 1.2. Analogous to the polymerization of para-phenylenediamine sulfate with terephthalic acid in SO3 reported previously, sulfonation of the aromatic diamine ring of S-PPT was not competitive with the polymerization reaction, but it was a major side reaction.
