Reaktionsschritte

13.62 g (0.2 mol) of imidazole was melted at 95° C., and 47.27 g (0.2 mol) of (3-glycidoxypropyl)trimethoxysilane was added dropwise thereto over a period of 30 minutes while stirred in an argon atmosphere. Following addition, the product was further reacted for one hour at a temperature of 95° C., yielding an imidaz,ole group-containing silane coupling agent comprising a mixture of the compounds represented by the chemical formulas (1), (2), and (3) below. In the formulas (1), (2), and (3) below, R1, R2, and R3 are H; R4 is CH3; n is 3; and m is 3. 2.16 g (0.04 mol) of the imidazole group-containing silane coupling agent thus obtained, 8.64 g (0.06 mol) of 2-phenylimidazole (melting point: 137-147° C.), and 21.0 g (0.1 mol) of trimellitic acid were heated and mixed at 160° C., the reaction was continues for one hour, and the product was cooled to room temperatures, yielding an imidazole trimellitate composition that was solid at normal temperature. The solid product thus obtained was ground with a mortar and classified by a sieve with hole openings of 90 microns to yield pulverized Sample No. 1.
