(3-Aminopropyl)triethoxysilane → Bis[2-(2-methacryloyloxyethoxycarbonyl)-ethyl]-(3-triethoxysilylpropyl)amine

Participants

Reaction Steps

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.
