Provided are: a curable composition from which a cured article having excellent molding processability and high heat resistance as well as such a high Tg that it can be used as a molding resin for a SiC power semiconductor can be obtained; and a cured article thereof. The curable composition comprises: 100 parts by mass of a compound having at least two partial structures represented by the following Formula (1) in the molecule as a component (A); 0.5 to 3 parts by mass of a thermal radical generator as a component (B); and 0 to 50 parts by mass of other radical-reactive compound as a component (C):
(wherein, ring A represents a benzene ring or a cyclohexyl ring; R1 represents an alkylene group having 1 to 6 carbon atoms; R2 represents an alkyl group having 1 to 4 carbon atoms; a represents a number of 0 or 1; b represents an integer of 0 to 3; and c represents a number of 1 or 2).
本发明提供了:一种可固化组合物,通过该组合物可以获得一种固化物,该固化物具有优异的成型加工性和高耐热性,并且具有很高的 Tg,可以用作碳化硅功率半导体的成型树脂;以及一种固化物。固化组合物包括100 份(质量)分子中至少有两个部分结构由下式 (1) 表示的化合物作为组分 (A); 0.5 至 3 份(质量)热自由基发生器作为组分 (B);以及 0 至 50 份(质量)其他自由基反应化合物作为组分 (C):
(其中,环 A 代表苯环或环己基环;R1 代表具有 1 至 6 个碳原子的亚烷基;R2 代表具有 1 至 4 个碳原子的烷基;a 代表 0 或 1;b 代表 0 至 3 的整数;c 代表 1 或 2)。
