There is disclosed an epoxy composition containing at least two kinds of epoxy compounds selected from the epoxy compounds of the formula (1) :
wherein
each of Ar1, Ar2 and Ar3, the same as or different from one another, is a bivalent group of any one of the following formulas:
wherein R is a hydrogen atom or a C1-8 alkyl group; a is an integer of 1 to 8; each of b, e and g is an integer of 1 to 6; c is an integer of 1 to 7; each of d and h is an integer of 1 to 4; and f is an integer of 1 to 5, wherein, when there are present a plurality of Rs in said bivalent group, Rs may be all the same groups or may be different groups from one another;
Q is a C1-8 linear alkylene group, wherein a methylene group constituting the linear alkylene group may be substituted with a C1-s alkyl group, and wherein a methylene group, not adjacent to an oxygen atom, may be replaced by - O-, and -O- or -N(R4)- may be inserted between methylene groups;
each of R1, R2, R3 and R4, the same as or different from one another, is a hydrogen atom or a C1-8 alkyl group;
m is 0 or 1; and
n is an integer of 0 to 10.
本发明公开了一种环氧组合物,其中含有至少两种选自式(1)环氧化合物的环氧化合物:
其中
Ar1、Ar2 和 Ar3(相同或不同)各自是下列任何一种式子的二价基团:
其中 R 是氢原子或 C1-8 烷基;a 是 1 至 8 的整数;b、e 和 g 中的每一个是 1 至 6 的整数;c 是 1 至 7 的整数;d 和 h 中的每一个是 1 至 4 的整数;f 是 1 至 5 的整数,当所述二价基团中存在多个 Rs 时,Rs 可以是相同的基团,也可以是彼此不同的基团;
Q 是 C1-8 直链亚烷基,其中构成该直链亚烷基的亚甲基可被 C1-s 烷基取代,不与氧原子相邻的亚甲基可被-O-取代,亚甲基之间可插入-O-或-N(R4)-;
相同或不同的 R1、R2、R3 和 R4 中的每一个都是氢原子或 C1-8 烷基;
m 是 0 或 1;以及
n 是 0 至 10 的整数。
