Abstract
The present disclosure provides a method for producing a benzoxazine compound by reacting a bi-functional phenol with formaldehyde and a mono-functional amine in the presence of a solvent system containing an apolar solvent and a polar aprotic solvent. Once formed, the benzoxazine compound may be precipitated from the reaction solution and dried to form a benzoxazine compound in powder form.
