Abstract: Anew spiro ortho carbonate 3,9-di(p-methoxybenzyl)1-1,5,7,11-tetroxaspiro[5,5] undecane(1)was prepared. Its cationic polymerization was carried out. The 1H NMR, 13C NMR and IR data as well as elemental analysis of the obtained polymers indicated that it underwent double ring opening polymerization. The polymerization mechanism was discussed. DSC and IR were used to trace the curing process of epoxy resin with or without this monomer. The effects of curing agent and curing condition on curing reaction were investigated.

Key words: spiro ortho carbonate, cationic polymerization, double ring-opening polymerization, epoxy resin, curing reaction
