Reaktionsschritte

Pentaerythritol tetraacrylate (4.4 g, 0.0125 moles) was added to N-methylaniline (5.4 g 0.050 moles), dissolved in glacial acetic acid (10 ml). The mixture was heated with stirring at 100° C. for 2 hours and then the acetic acid removed by vacuum distillation. An infrared spectrum of the residual oil revealed the presence of a little unreacted N-methylaniline but little sign of any unreacted acrylate groups. Absorptions due to the presence of a saturated ester (1730 cm−1) and an aromatic amine (1600 cm−) were found. 1H NMR δ 2.6 (CH2—CO, 8H t), 2.9 (CH3—N 12H s) 3.6 (CH2—N, 8H, t), 4.1 (CH2—O 8H s), 6.7 (aromatic protons 12H) 7.2 (aromatic protons 8H).
