Abstract
Three homopolycyanurates were synthesized by stirred interfacial polycondensation of 2-morpholino-4,6-dichloro-s-triazine with each of three aromatic diols viz. bisphenol-A (BPA), bisphenol-C (BPC) and bisphenol-S (BPS). Three copolycyanurates were synthesized using each of the following mixtures of diols: (BPA + PBC), (BPC + BPS) and (BPA + BPS). Polymer yields were in the range 65–83%; products were characterized by density, viscosity measurements, i.r. spectra, solubility tests and thermogravimetric analysis. The polymers had reduced viscosities in the range 0.45–0.84 dl/g in chloroform at 30°. All the polymers were amorphous and soluble in chlorinated solvents. Homopolycyanurate derived from BPC and copolycyanurate derived from BPA and BPC showed greater thermal stability than the others.
