✦ Synopsis

Poly-Schiff base containing bisthiazole rings (TAPDA) has been prepared from terephthalaldehyde and 2,2 -diamino-4,4-bisthiazole. It was found that the TAPDA polymer film is permeable to H 2 , O 2 , and N 2 and can be converted into an electrical conductor by pyrolysis at high temperature in nitrogen. TAPDA is a novel chelate polymer. The complex of Cu(II) with TAPDA was readily obtained; and the noble metal ions Au(III), Pt(IV), Pd(II), and Ag(I) can be adsorbed quantitatively by the TAPDA powder.
