Miller et al., Electrooptic properties of side-chain polyimides with exceptional thermal stabilities CONCLUSION GENERALE ET PERSPECTIVES Annexe Protocoles de Synthèses Synthèse de 2-bromomethylthiophène Dans un ballon de 250 mL équipé d'un réfrigérant, on mélange 10 g de 2- methylthiophène (0,102 mol) et 16, 3 g de N-bromosuccinimide (0,092 mol) dans 120 mL de tétrachlorométhane, et on introduit 0,4 g de peroxyde de benzoyle. On chauffe à 75 °C pendant 2 h sous atmosphère d'azote. Après refroidissement, on filtre la solution, Macromolecules, vol.2870, pp.4970-4975, 1995.
