POLYMERS AND PROCESS FOR THEIR MANUFACTURE

Disclosed are polymers, a process for manufacturing polymers and uses of the polymers. The polymers are polyaryl ether ketones and the process includes a nucleophilic polycondensation of a bisphenol with an organic dihalide compound in a reaction mixture comprising sodium carbonate and potassium carbonate, in an aromatic sulfone solvent, at a reaction temperature rising to a temperature from 290 DEG C to 320 DEG C immediately prior to the addition of a salt to the reaction mixture, wherein the molar ratio of the salt to potassium carbonate is from 6.0 to 10.0. Further organic dihalide compoundis added to the reaction mixture in which the molar ratio of further organic dihalide compound to bisphenol is from 0.009 to 0.035. The resulting reaction mixture is maintained at a temperature at from 290 DEG C to 320 DEG C for from 20 to 180 minutes and then the resulting reaction mixture is cooled and the PAEK recovered. 公开了聚合物、用于制造聚合物的方法和所述聚合物的用途。所述聚合物为聚芳醚酮，并且所述方法包括在升高到290℃至320℃的温度的反应温度下在芳族砜溶剂中在包含碳酸钠和碳酸钾的反应混合物中使双酚与有机
