Abstract To explore the influence of substituent groups on thermally induced curing, eight new bio-based benzoxazines
containing different substituent groups with different electron negativity and volumes were synthesized. The thermal curing of these bio-based benzoxazines was studied in detail. Combined with the curing reaction kinetics,
simulation and calculation of Highest Occupied Molecular and Lowest Unoccupied Molecular values, the spatial
and electronic effects of different substituent groups on the curing of benzoxazine was explored. It was found that
when the substituent was located at the position directly connected to the N atom, the steric hindrance effect of… More >
