| titleOfInvention | Recovery and reuse of activators and initiators following polycarbonate synthesis |
| abstract | Methods of recovering and/or reusing activators and/or initiators following polycarbonate synthesis may include: contacting an amine compound with a carboxylic acid compound to form a first ammonium salt including a first ammonium cation associated with a carboxylate group; mixing the first ammonium salt with a reaction solution to obtain a first solution comprising a protonated polycarbonate, an activator adduct, and a second ammonium salt in which the second ammonium cation is associated with the carboxylate group from the first ammonium salt; contacting the first solution to precipitate the polycarbonate out of solution; separating the activator adduct from the precipitated polycarbonate and the second ammonium salt to obtain a second solution; separating the precipitated polycarbonate from the second ammonium salt to recover the second ammonium salt; and separating the activator adduct from the second solution to recover an activator capable of being reused for synthesizing additional polycarbonates. |
