Abstract

FTIR and Raman spectra of melaminium cyanoacetate have been recorded and analyzed. Band assignments are given based on the melamine and cyanoacetic acid molecules. The ring breathing vibrations of the triazine ring show frequency shift toward the high wavenumber side. This change is attributed to an increase in rigidity of the ring as a consequence of protonation and the formation of donor–acceptor types of hydrogen bonding interactions. Notably, this melaminium cyanoacetate salt also contributes to the efficient flame-retardant properties of polyurethane foam substrate as revealed by the flammability test and thermogravimetric analysis.
