HETERO-AROMATIC-FLUORESCENT POLYESTERS: SYNTHESIS, CHARACTERIZATION AND PHYSICAL STUDY

Abstract

A new class of high performance hetero-aromatic-fluorescent polyesters containing coumarin and s-triazine rings was\ prepared by high temperature condensation polymerization technique using cetrimide as initiator at 170-180°C. All the polyesters were characterized by IR and 1H NMR spectroscopy. The inherent and reduced viscosities were checked by Ubbelohde solution viscometer and intrinsic viscosity was measured using Huggins and Kraemer’s equations. Solubility of all the polyesters was checked in polar and nonpolar solvents. Density of all the polyesters was counted by pycnometer. Thermo gravimetric analysis of all the polyesters has been carried out in air. The obtained polyesters have shown fluorescent property due to coumarin ring.
