摘　　要：A new kind of thiazole-containing unsymmetrical ortho-diamine monomer, 2-amino-5-[4-（2＇- aminophenoxy）phenyl]-thiazole （o-AAPPT）, was synthesized by four steps, using 4-hydroxyacetophe- none as starting material. A novel thiazole-containing polyimide was prepared from the resulting diamine o-AAPPT with BTDA via a conventional one-step method. The resulting polyimide exhibits excellent solubility, film-forming capability and high thermal and thermo-oxidative stability.A new kind of thiazole-containing unsymmetrical ortho-diamine monomer, 2-amino-5-[4-（2＇- aminophenoxy）phenyl]-thiazole （o-AAPPT）, was synthesized by four steps, using 4-hydroxyacetophe- none as starting material.
