الملخص

In this research, two ether derivatives of phenolic azo dyes were synthesized via Williamson's reaction according to the S_N2 mechanism. The prepared compounds were radically polymerized using (AIBN) as an initiator and their structures were identified by FT-IR and ¹H-NMR. Furthermore, thermal properties of these polymers was made by (DSC). Bandgap energy have been calculated to indicate the ability of these polymers as optical semiconductors, it was 2.8ev, 2.4ev for P(AO₂) and P(AON₁) respectively. Beside the determination of refractive index, kinematic viscosity, density, and degree of Turbidity.
