| Abstract: | The trihydric alcohol synthetized in laboratory reacted with dibutyltin oxide to generate ex- panding monomer with spiro structure （ 3,9-dihydroxytoluene-3,9-bis （ dimethylethanethial ） - 1,5,7,11 -te- traoxaspiro 5,5 ] undecane）, to solve the adverse effects of volume shrinkage during the curing reaction of epoxy resin. The products were confirmed by IR and NMR characterization. Volume expansion rate of the cationic initiator ring-opening polymerization was 3.16 %, measured with expansion agent. Volume expansion rate of modified epoxy resin with prepolymer was 1. 194 %. |
