Abstract

A novel class of photopolymerizable benzoxazines has been developed. This class has been coined as methacryloyl-functional benzoxazines. It has been synthesized by the reaction of the new benzoxazine monomers: (3-phenyl-3,4-dihydro-2H-benzo[e][1,3]oxazin-6-yl)methanol and methacryloyl chloride. The structure of the monomer has been confirmed by Fourier transform infrared spectroscopy (FTIR) and 1H and 13C nuclear magnetic resonance spectroscopy (NMR). Its photopolymerization has been successfully carried out with and without photoinitiator, while the thermally activated polymerization is compromised by low temperature degradation.
