摘要：

Two arylpropargyl ether terminated monomers have been synthesized, (p HC = CCH2OC6H4)2CMe2 (I) and the analogous model monomer pHC = CCH2OC6H4CMe2Ph (II) having a single arylpropargyl ether group. DSC, i.r., H-1- and C-13-NMR analysis of the products resulting from partial cure of I and complete cure of II showed that the crosslinking involves prior sigmatropic rearrangement of the arylpropargyl ether groups to 2H-1-benzopyran structures which subsequently polymerize. The various intermediate 2H-1-benzopyran-containing species were isolated and characterized.
