4-Bis[4-(2-amino-4-phenyl)thiazoleyl] benzene wasfirstsynthesized from 1

4-bis(benzeneacetyl) benzene. The synthetic routes are shown in thefollowing equations : The structure of 1

4-bis[4-(2-amino-4-phenyl)thiazoleyl]benzene was confirmed by IR

1H-NMR

13C-NMR and elementalanalysis. The novelpolyimide(TIB) and copolyimide(TIBO)containing thiazole ring were prepared by reacting 1

4-bis[4-(2-amino-5-phenyl)thiazoleyl]benzene or/and 4

4′-diaminodiphenyl ether with 3

3′

4

4′-benzophenone tetracarboxylic dianhdride. Their films exhibited good thermal oxidative stability. The decomposition temperatures in air and in nitrogen were 499

488℃ (for polyimide) and 510

498℃copolyimide

respectively. The copolyimide (TIBO) film was converted into electrical conductor by pyrolysis at 1200℃ was as high as 64S/m and is was very stable in air.
