    摘要: Disclosed is a novel terminally modified imide oligomer having excellent solubility in organic solvents, excellent solution storage stability, and excellent molding properties such as low melt viscosity. Also disclosed are a varnish obtained by dissolving the terminally modified imide oligomer in an organic solvent; a cure product obtained by using the terminally modified imide oligomer and having excellent thermal and mechanical characteristics such as heat resistance, elastic modulus, tensile strength at break and tensile elongation at break; a prepreg; and a fiber-reinforced laminate. The soluble terminally modified imide oligomer is represented by general formula (1). (In the formula, R 1 and R 2 each represents a divalent aromatic diamine residue; R 3 and R 4 each represents a tetravalent aromatic tetracarboxylic acid residue; R 5 and R 6 each represents a hydrogen atom or a phenyl group, with R 5 or R 6 being a phenyl group; m and n satisfy the following relations: m ≥ 1, n ≥ 0,1 ≤ m + n ≤ 20 and 0.05 ≤ m/(m + n) ≥ 1; and the repeating units may be arranged in blocks or randomly.)
