Abstract

The benzoxazine monomer is used to simplify the study of the benzoxazine initiation mechanism. The HPLC retention time and the 1H NMR spectra of crude products from the benzoxazine reaction are compared with the results from a vast number of pure model compounds, which are synthesized based on the hypothesized mechanisms. Products involved in the process are identified, with species having benzoxazine structures, ...
