Abstract

A new series of polyamides based on diarylidene derivatives were synthesized from 2,5-bis(m-aminobenzylidene)cyclopentanone VIII, 2,6-bis(m-aminobenzylidene)cyclohexanone IX, 2,7-bis(m-aminobenzylidene) cyclheptanone X and bis(m-aminobenzylidene) acetone XI by reaction with diacid chlorides of thianthrene (2,7- Dichloroformylthianthrene -5,5`,10,10`-tetraoxide IV. using solution polycondensation technique. These polymers ranged from yellow to orange color and had inherent viscosity up to 1.08-0.65 dL/g. All the polyamides were insoluble in common organic solvents but dissolved completely in concentrated H2SO4. The thermal stabilities of the prepared polyamides were evaluated by TGA and DSC analyses. The morphological properties of some selected polyamides were detected by SEM.
