An organosilicon compound represented by formula (1), which has, per alkoxysilyl group, a plurality of epoxy groups each capable of reacting with an organic resin moiety to form a bond and which hence is useful as a primer, a resin modifier, etc.
(In the formula, the R1 moieties each independently represent an (un)substituted C1-10 alkyl group, etc.; the R2 moieties each independently represent an (un)substituted C1-10 alkyl group, etc.; the R3 moieties each independently represent a hydrogen atom or a methyl group; A1 represents a single bond, O, S, NH, or a divalent linking group containing a heteroatom; A2 represents a single bond or an (un)substituted C1-20 divalent hydrocarbon group optionally containing a heteroatom; a and c are each independently a number greater than 0; b, d, e, and f are each independently a number of 0 or greater; and m is an integer of 1 to 3. The repeating units may have been linked in any order.)
一种由式(1)表示的有机硅化合物,其每个烷氧基硅烷基上都有多个环氧基团,每个环氧基团都能与有机树脂分子反应形成键合,因此可用作底漆、树脂改性剂等。
(式中:R1 各独立地代表一个(未)取代的 C1-10 烷基等;R2 各独立地代表一个(未)取代的 C1-10 烷基等;R3 各独立地代表一个(未)取代的 C1-10 烷基等;R4 各独立地代表一个(未)取代的 C1-10 烷基等;R5 各独立地代表一个(未)取代的 C1-10 烷基等。A1 代表单键、O、S、NH 或含有杂原子的二价连接基团;A2 代表单键或任选含有杂原子的(未)取代的 C1-20 二价烃基;a 和 c 分别独立地为大于 0 的数字;b、d、e 和 f 分别独立地为 0 或大于 0 的数字;m 为 1 至 3 的整数。)
