实验步骤: 43 g (0.25 mol) 3-aminopropyl triethoxysilane in 40 ml anhydrous acetonitrile are added dropwise accompanied by ice-cooling to 92 g (0.5 mol) 2-acryloyloxyethyl methacrylate in 85 ml acetonitrile. After 48 h stirring at room temperature, the aminosilane has completely reacted. The solvent is evaporated off accompanied by the introduction of air at reduced pressure at the rotary evaporator at maximally 46° C. 132.2 g (98% yield) of a lightly-coloured clear oily liquid are obtained. The solvent is evaporated off accompanied by the introduction of air at reduced pressure at the rotary evaporator at maximally 46° C

实验步骤: Preferably, Route A can be used. A chloromethylated ligand can be prepared, for example, by reacting 8-hydroxyquinoline with formaldehyde and hydrochloric acid. That derivative is further reacted with γ-aminopropyltriethoxysilane in the presence of trimethylchlorosilane and triethylamine and nitrobenzene. Next, the prepared organosilicon derivative is reacted with the support to obtain hydroxyquinoline modified silica gel. A sample of this sequence of reactions is described in further detail in Example 2 below.

实验步骤: Into a sealable, glass container were charged 50 g of γ-aminopropyl-triethoxysilane (0.226 mole) and 50 g (0.694 mole) methyl ethyl ketone. The mixture was allowed to stand one hour to permit the ketimine to form. Then 106.8 g (0.4525 mole) of γ-glicidoxypropyl-trimethoxysilane, 117.2 g of methyl ethyl ketone (1.63 mole) and 12.4 g (0.678 mole) distilled water were added to the ketimine mixture (representing a molar ratio of water per siloxane group of 0.68). The non-volatile solids content was 45 wt. % of the total coating composition, which was composed of the first component, or ketimine, and the second component (formed via partial hydrolysis of the γ-glycidoxypropyl-trimethoxysilane). The coating composition was allowed to age for about one hour, and then a sample was drawn down onto a degreased panel of polyallyl diglycol carbonate with a #22 wire wound coating rod. The coating was cured by baking at 15 hours at 80° C. The adhesion, as tested by ASTM D3359, was 100%. The scratch resistance on a Gardner Labs Scratch and Adhesion Tester was 148 g.
