Abstract: The present invention relates to preparation of clear adhesive material. The Phosphazene-based clear adhesive material which comprised of cyclophosphazene, biphenols and aromatic ester groups possess especial optical and thermal characteristics. When adequate amount of Phosphazene-based clear adhesive material applied between two glass surfaces, it affords high optical transparency of at least 90% in the visible wavelengths at the range of 400-700 nm and good adhesive strength, thermo and photo oxidative stability. Phosphazene-based clear adhesive material is a thermoplastic and it offers a possibility of repeatedly disbonding and re-bonding of glass plats once exposed to heat.
