Abstract

Commercially available aromatic diamines such as 4,4'-oxydianiline and 4,4'-methylenedianiline were treated with N-acetamidobenzenesulfonyl chloride to give the amino-sulfonamido-acetanilide derivatives. These derivatives were treated with 6M hydrochloric acid to give the demine monomers containing a preformed sulfonamide linkage. These monomers were polymerized with various bisimide diacids using the Yamazaki reaction. Polymerizations involving a low temperature solution technique were also investigated. The polymers obtained were characterized using infrared spectroscopy, thermal gravimetric analysis, differential scanning calorimetry, and dilute solution viscosity. Inherent viscosities of the prepared polymers ranged from 0.08 to 0.54 dL/gm. In spite of low inherent viscosities, the polymers had film forming properties, with all but one being clear, flexible, and slightly colored. Glass transition temperatures, determined by differential scanning calorimetry, ranged from 266 to 324°C. Thermogravimetric analyses of the polymers showed that they have moderate thermal stability with polymer decomposition temperatures ranging from 361 to 417°C and weight losses ranging from 4.13% to 11.28% at 360°C in nitrogen.
