Title (EN) METHODS OF MANUFACTURE OF 2-ARYL-3,3-BIS(HYDROXYARYL)PHTHALIMIDINES
(FR) PROCÉDÉS DE PRODUCTION DE 2-ARYL-3,3-BIS(HYDROXYARYL)PHTALIMIDINES
Abstract:
(EN) A method for the manufacture of a 2-aryl-3,3-bis(hydroxyaryl)phthalimidine via O- alkylation of a dihydroxy benzophenone, and formation of Schiff base, followed by cyclisation and de-O-alkylation to provide the product phthalimidine is provided. Polymers including structural units derived from the 2-aryl-3,3-bis(hydroxyaryl)phthalimidine are provided. Methods for the manufacture of a polycarbonate, including manufacturing the 2-aryl-3,3- bis(hydroxyaryl)phthalimidine, and polymerizing the 2-aryl-3,3-bis(hydroxyaryl)phthalimidine in the presence of a carbonate source are provided.
(FR) L'invention concerne un procédé de production de 2-aryl-3,3-bis(hydroxyaryl)phtalimidine par O-alkylation d'une dihydroxybenzophénone et formation d'une base de Schiff, suivies d'une cyclisation et d'une désalkylation pour obtenir le produit phtalimidine. L'invention concerne également des polymères comprenant des motifs structuraux dérivés de la 2-aryl-3,3-bis(hydroxyaryl)phtalimidine. L'invention concerne en outre des procédés de production d'un polycarbonate, qui consiste à produire le 2-aryl-3,3-bis(hydroxyaryl)phtalimidine, et à polymériser la 2-aryl-3,3-bis(hydroxyaryl)phtalimidine en présence d'une source carbonate.
