Abstract: This paper investigated the improvement of adhesion property of epoxy resin using oligomers with end-capped spiro orthocarbonate. It was found that the addition of oligomers into epoxy resin system enhanced the conversion of epoxy groups and the tensile strength and shear strength of epoxy increased as the content of the oligomers increased.Slight reduction of fluxural strength and increase of elongation of the matrix were observed.The above phenomenon was discussed.

Key words: Spiro orthocarbonate, Oligomer, Modified epoxy resin, Adhesion property
