Abstract: An oligomer is formed by reacting a diacid monomer with (a) epoxy resin or (b) glycidyl methacrylate, wherein the diacid monomer has a chemical structure of




wherein X is —O—,





and each R1 is independently CH3, CH2F, CHF2, or CF3. A composition containing the oligomer can be cured to serve as a sealant of an optoelectronic device, and the sealant can be lifted off by a laser beam irradiation.
