Abstract
:
Hydroxy terminated polyesters were synthesized by the reaction of tetrabromophthalic, phthalic, and maleic anhydrides with polyethylene glycol via melt condensation technique. They were characterized by hydroxyl number and intrinsic viscosity measurements.Also, the fire retardancy of polyesters was reacted with excess toluene-2, 4-diisocyanate to yield isocyanate terminated prepolymers which were subsequently reacted with 5,5-dihydroxymethyl-2-trichloromethyl-1,3-dioxane or ethylene diamine. These polymers were characterized by IR and 1H NMR spectra, viscosity measurements, and thermogravimetric analysis. A change of the electrical conductance of the compounds with increasing temperature is observed for the solid samples.
