Abstract
PURPOSE: To obtain aromatic polyester of high degree of polymerization and high purity with high yield, by reacting a quinone compound with a dicarboxyl dihalide under a reducing condition.
CONSTITUTION: To an dispersion of the equivalent quinone (e.g. anthraquinone) in water are dissolved 1W100 equivalent reducing agent (e.g. Na2SO3) and 2W 100 equivalent alkaline compound (e.g. NaOH). Subsequently to the solution is added a solution of 1W10 equivalent dicarboxyl dihalide (e.g. adipoyl dichloride) and a surface active agent (e.g. benzyltrimethylammonium halide) in a hydrophobic solvent (e.g. chloroform), and the mixture after reacting at -10°CW100°C for 1minW10hr is poured into methanol or water to precipitate the purpose aromatic polyester.
