The paper described the modification of epoxy resin using a new prepolymer containing spiro orthocarbonate. It was found that the addition of prepolymer into epoxy resin system enhanced the conversion of epoxy groups and the Tg and thermal stability of the matrix were slightly reduced. The adhesive tensile and shear strength of the modified epoxy resin increased obviousely as the content of the prepolymer increased. The above observed phenomena were discussed
and the relationship between shrinkage and adhesive strength was investigated.
