Synthesis and Characterization of Benzoxazine Monomers Based on Triethoxysilyl Propyl Amine, and their polymerization and Studying of their Thermal Stability

In this work, three new compounds of benzoxazine monomers were synthesized based on (phenol, hydroquinone, 2-naphthol) and triethoxysilyl propyl amine (TESPA) and paraformaldehyde. (TESPA) were used to study its effect on the thermal stability of polybenzoxazine resulting from the ring opening polymerization of prepared monomers.
