In this paper, adduct polymer was prepared by additive reaction of maleic anhydride or succinic anhydride to liquid hydroxy terminated polybutadiene (HT-PB) and it was examined whether the adduct polymer could be crosslinked with various metallic oxides and metallic hydroxides or not.As the result, the relationship between the ability of ionic crosslinking and the kind of metallic compounds was not made clear, but it was found that zinc oxides were better ionic crosslinking agents than the other metallic compounds. The cured adduct polymer was opaque and its tensile strength was low.In the presence of carbon black, the adduct polymer cured with white carbon and zinc oxide had better mechanical property than ones cured with zinc oxide, and indicated the characteristics of ionomer that the elongation at high temperature is larger.
