Abstract

The paper describes some physical properties of poly(ether-amide)s (PEAs) prepared by solution polycondensation reaction of ether-amines such as 2,7-bis(4-aminophenoxy) naphthalene, 2,2-bis[4-(4- aminophenoxy)phenyl] propane, 1,4-bis(4-aminophenoxy methyl) cyclohexane and isophthalic acid. Resulting PEAs are high yield and have inherent viscosity ranging between 0.68–0.75 dL/g. The etheramines containing wholly, semi aromatic and aliphatic-aromatic segments were prepared by using two steps reaction. FTIR, 1H NMR, and elemental analyses were used for characterization of synthetic ether-amines and poly(ether-amide)s. PEAs films were prepared by solution casting technique then their thermal stability and mechanical properties were measured. TGA in nitrogen atmosphere shows that the PEAs are thermally stability, so 10% weight will be lost in the range of 335–358°C. Tensile strength and elongation at break of the PEA films ranged from 71.1–65.0 MPa and 6.48–8.41%, respectively.
