Bisphenol-A is converted to indane bisphenol and spirobiindane bisphenol. The compounds bisphenol-A benzoxazine (BAB), indane bisphenol benzoxazine (IBPB), and spirobiindane bisphenol benzoxazine (SBIB) are prepared by condensing the respective bisphenols with paraformaldehyde and aniline. The structural characterization of the synthesized materials is done by using FTIR, 1H, and 13C NMR. Curing behavior of these benzoxazines and glass transition temperature for polybenzoxazines are studied…
