الثبات الحراري لمادة البولي أميد الجديدة التي تحتوي على مادة 1-Phenethyl-4-Piperidone في السلسلة الرئيسية

A new polyamide based on pyridine moiety was synthesized from 3,5-bis(4-aminobenzylidene) -1-Phenethyl-4-Piperidone (II) by reaction with 2,6-Pyridinedicarbonyl chloride using solution polycondensation technique. The polymer was obtained has yellow color and had inherent viscosity 0.86 dL/g. The solubility of polyamide was insoluble in common organic solvents but dissolved completely in concentrated H2SO4. The thermal properties of the polyamide was evaluated and correlated to their structural units by TGA and DSC measurements. Electrical conductivity in the range of 2.4 X 10-11 Ω-1 cm-1.at room temperature.
