Abstract
AbstractPolyamides containing arylene sulfide as well as arylene sulfide‐sulfone linkages were prepared from bis(4‐phenylthio)dibenzoyl chloride (BPCl), 4,4′‐[sulfonylbis(4‐phenylthio)]dibenzoyl chloride (SPCl) and aromatic diamines both by solution and interfacial polymerization techniques. In the solution polymerization the effect of two different acid acceptors, lithium chloride and triethylamine, on inherent viscosity of the polyamides was studied. The effect of aromatic sulfone ether diamines and conventional aromatic diamines on viscosity and thermal properties of polyamides was also investigated. The polyamides prepared were characterized by IR, 1H NMR, elemental analysis, solution viscosity, thermogravi‐metry, differential scanning calorimetry and X‐ray diffraction. Thermal and physical properties of polyamides prepared from BPCl and SPCl were compared.
