WebFeb 1, 1999 · Phenyl propargyl ethers are known to undergo Claisen type sigmatropic rearrangement to 2H-chromenes (2-H-1-benzopyrans) 11, 12, 13. The uncatalysed rearrangement, in bulk is normally effected at higher temperature and is nearly always accompanied by thermal polymerisation of the formed chromene. WebNovel benzoxazine monomers containing arylpropargyl ether were prepared, and highly thermally stable polybenzoxazines were obtained by the thermal cure of the monomers. One monomer is a monofunctional benzoxazine, 4-propargyloxyphenyl- 3,4-dihydro-2H-1,3-benzoxazine (P-appe), and the other is a bifunctional benzoxazine, bis(4 …
