Provided are: a soluble polyfunctional vinyl aromatic copolymer which has improved heat resistance, thermal decomposition resistance, solubility in solvents, processability and compatibility with specific resins; and a curable composition of this soluble polyfunctional vinyl aromatic copolymer .nA soluble polyfunctional vinyl aromatic copolymer which contains a repeating structural unit derived from a divinyl aromatic compound (a) and a repeating unit derived from a monovinyl aromatic compound (b), and which is characterized in that, the repeating structural unit derived from a divinyl aromatic compound (a) is a unit having an unsaturated hydrocarbon group, which is a vinyl group-containing unit and/or a vinylene group-containing unit; and the copolymer has, as a terminal group, a vinylene group-containing terminal group that is derived from the divinyl aromatic compound (a) and/or the monovinyl aromatic compound (b). This soluble polyfunctional vinyl aromatic copolymer is also characterized by being polymerizable and by being soluble in a solvent. |
