| titleOfInvention | Improved polyamide acids, polyimides, poly(esterimides) |
| abstract | Aromatic or aliphatic dianhydrides and/or acid anhydrides are reacted with aromatic diamines of formula (a) alone or in combination with other diamines to produce polyimides, polyamide acids, poly(amide-imides), poly(amide-amide acids), poly(esterimides) or poly)esteramide acids). These polymers are thermoplastic in nature and have improved processing characteristics and thermal stability. The polymers may be prepared by either melt or solution polymerization techniques.wherein R<sup>1</sup>, R<sup>2</sup> and R<sup>3</sup> each independently is hydrogen, halogen or unsubstituted or substituted hydrocarbyl,X<sub>1</sub> and X<sub>2</sub> each independently is substituted or unsubstituted branched, linear or cyclic alkylene or alkenylene of 1 to about 30 carbon atoms, -S-, or -O- with the proviso that X, or X<sub>2</sub> and may not both concurrently be -S- or -0-.n, n' and n" each independently is an integer of 1 to 4. |
