Synthesis and Physicochemical Studies of Some Novel Homopolyesters Based on s-Triazine

Abstract

The diacid chloride 2-(N-methyl piperazine)-4,6-bis(2-naphthoxy-6-carbonyl chloride) [MPNCCT] has been synthesized, from which different homopolyesters have been made by polycondensation with the following diols: bisphenol-A [BPA], bisphenol-C [BPC], bisphenol-S [BPS], 1,4-dihydroxy anthraquinone [1,4-DHA], 1,8-dihydroxy anthraquinone [1,8-DHA], catechol [C], resorcinol [R], phenolphthalein [Ph], ethylene glycol [EG] and diethylene glycol [DEG]. All the synthesized polyesters were characterized by solubility, density, viscosity measurements, IR spectra, NMR spectra and thermogravimetric analysis [TGA].

Keywords:

• density
• homopolyesters
• physicochemical
• solubility
• synthesis
• viscosity

The authors express their sincere gratitude to the Head of the Department of Chemistry, Veer Narmad South Gujarat University, Surat, for providing necessary research facilities.

Notes

The first and second symbol indicates the solubility of polymer at R.T. and 50°C, respectively + = Soluble, − = Insoluble, ± = Partly soluble.

∗Concentration of solution is 1 g/dl for all polymers.
