Synthesis and Characterization of Some New Copolyester from Curcumin Mono-Carbonyl Analogues

Nine copolyesters were prepared from a dicarboxylic acid, curcumin analogues (monocarbonyl) and phenophthalene dye in the mole ratio of 2:1:1 by direct polycondensation using triethylamine (Et3N) as condensation agent. The used is 2,6-Pyridine dicarbonyl dichloride acid. acid catalyzed Aldol reaction. These characterized FT-IR. fluorescence synthesized was also investigated. Furthermore, Thermo gravimetric analysis (TGA) to investigate thermal stability these copolymers.
