Disclosed are benzoxazine compositions where oxazine rings are part of the polymer main-chain. The benzoxazine oligomers are prepared by the reaction of a bisphenol and an aldehyde, such as formaldehyde or paraformaldehyde, with one or more diamines or polyamines, and optionally with one or more monofunctional amines or monofunctional phenols. Also disclosed are benzoxazine monomers prepared from a bisphenol, an aldehyde, such as formaldehyde or paraformaldehyde, and a monofunctional amine, which benzoxazine monomers may be optionally used as reactive diluents. Further disclosed are benzoxazine monomers are prepared from a diamine, and aldehyde, such as formaldehyde or paraformaldehyde, and a monofunctional phenol, which benzoxazine monomers may also be optionally used as reactive diluents.
