| Abstract: | A novel thermosetting 3-phenyl-3,4-dihydro-8-allyl-2H-1,3-benzoxazine (abbreviated as allyl benzoxazine hereafter) was synthesized successfully in several solvents by a solution method with 2-allyl phenol as raw materials. Its composition and structure were characterized by 1H-NMR,FT-IR,MS and Element Analysis and its curing behavior was investigated by different scanning calorimetry (DSC). The result showed that the composition of allyl benzoxazine was dependent on the polarity of the reaction medium.The stronger the solvent polarity is, the less the ring content is. |
