Thermal Behaviour and Fibre Studies of Certain New Aromatic – Aliphatic Polyamides

Download this article as: 

Thirteen polyamides were synthesized by polycondensation using phosphorylation, low temperature solution and interfacial solution methods from 2, 2’-Dichloro-4, 4’-diaminoazobenzene condensed with different aliphatic diacids. These were characterised by inherent viscosity, solubility and spectral studies like UV-visible and IR. Moisture regain and dyeing properties have also been studied. TGA and DTA were reported. X-ray and mechanical properties of the fibres extruded were also studied.
