SYNTHESIS AND POLYCONDENSATION OF SOME NEW ORGANIC TELLURIUM COMPOUNDS CONTAINING MONO-AMINO AND DI-AMINO GROUPS

Several new and known organic tellurium compounds containing amino gro ups (i.e. ArTeBr3, Ar2Te2 and Ar2Te, where Ar = 4-NH2C6H4, 2-NH2C6H4, 4-CH3CONHC6H4 or 2-NH2-5-NO2-C6H3) were prepared by reacting aminoaryl mercury chlorides with tellurium tetrabromide in glacial acetic acid, Bis(4-aminophenyl) telluride and bis(2-amino-5-nitrophenyl) telluride were polymerized with aromatic and aliphatic diacid chlorides (i.e. te rephthaloyl chloride and sebacoyl chloride), as well as with toluene d iisocyanate, leading to new organic tellurium polyamides and polyurea, All organic tellurium compounds and their condensation polymers were characterized by elemental analyses, IR, H-1 and C-13 NMR, and mass sp ectroscopy, The thermal stabilities of the resulting polymers were det ermined by thermogravimetric and derivative thermogravimetric techniqu es.
