A novel form of benzoxazine monomer has been successfully synthesized and polymerized. Previous methods have used the combination of different amines and phenols resulting in limited specificity. These methods limit the addition of functional groups to only the nitrogen and oxygen groups of the oxazine ring. Use of a novel three step method allows for a more precise addition of functional groups on to the -CH<sub>2</sub> regions of the oxazine ring allowing for a wider variety of polymers. The concept proven with monofunctional benzoxazine has been applied to make a difunctional form of benzoxazine. The novel monomer has successfully been polymerized and has been confirmed via DSC thermogram, an exothermic peak was observed at 237 <sup>o</sup>C. Benzoxazine’s high glass transition, char yield, and degradation temperature give this a class of polymer many unique advantages over most known polymers today. They also exhibit low water absorption along with a low dielectric constant which makes them a good candidate for electronic packaging and aerospace industries.
