There is provided a novel cyanate ester compound which has excellent solvent solubility and provides a hardened product having a low coefficiency of thermal expansion, and excellent flame retardancy and heat resistance. The present invention is a cyanate ester compound represented by the following formula (1):
wherein Ar represents an aromatic ring; R1 each independently represents a hydrogen atom, an alkyl group, or an aryl group; n each independently represents an integer of 1 to 3; m + n is the same as the total number of hydrogen atoms in a monovalent aromatic group containing the aromatic ring and the hydrogen atoms; R2 represents a hydrogen atom (excluding a case where Ar represents a benzene ring; n each represents 1; R1 represents a hydrogen atom; m each represents 4, and a cyanate group is bonded to the benzene ring in the 4-position relative to an adamantyl group), or an alkyl group having 1 to 4 carbon atoms; and R3 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
本发明提供了一种新型氰酸酯化合物,它具有极佳的溶剂溶解性,可提供热膨胀系数低、阻燃性和耐热性极佳的硬化产品。本发明是由下式(1)表示的氰酸酯化合物:
其中 Ar 代表芳香环;R1 各自独立地代表氢原子、烷基或芳基;n 各自独立地代表 1 至 3 的整数;m + n 与包含芳香环和氢原子的一价芳香基团中氢原子的总数相同;R2 代表氢原子(不包括 Ar 代表苯环的情况;n 各代表 1;R1 代表氢原子;m 各代表 4,相对于金刚烷基,氰酸酯基团键合在苯环的 4 位上)或具有 1 至 4 个碳原子的烷基;以及 R3 代表氢原子或具有 1 至 4 个碳原子的烷基。
