ABSTRACT:
This paper deals with the synthesis of new terpolymeric material by using oil bath. The material have been prepared by condensation of monomer i.e. orcinol,guanidine hydrochloride and formaldehyde in acidic medium (2 M HCl) in varying molar ratios. The sample was purified and then characterized bydifferetspectral methods like 1H-NMR, IR and UV-visible techniques to elucidate the structure oforcinol-guanidine hydrochloride-formaldehyde(OGF) material. The thermal degradation ability of OGF material was studied using thermogravimetric analysis (TGA) in a static nitrogen atmosphereat a heating rate of 100C/min. Freeman–Carroll and Sharp–Wentworth methods were used to calculate the thermal activation energy (Ea) and order of reaction (n).
Keywords:Terpolymeric material, orcinol, guanidine hydrochloride , formaldehyde, TGA.
