| titleOfInvention | Process for the production of high molecular weight optionally branched polyarylene sulfides |
| abstract | (57) [Summary] [Objective] A method for producing polyarylene sulfide (PAS) having a high content of extractable oligomer and monomer components, which may be optionally branched. [Structure] The reaction is carried out by mixing an aqueous solution of an alkali metal sulfide and / or an alkali metal hydrogen sulfide with an organic solvent solution of a dihalogenated aromatic compound at a temperature of 212 ° C. or higher to obtain a water content of the reaction solution. 0.02% by weight Unreacted halogenated aromatic compounds are removed continuously or at the end of the reaction from the reaction mixture, and an aqueous solution of the above alkali metal sulphides and / or alkali metal hydrogen sulphides is optionally added. Characterized in that it is introduced into the reaction mixture at high temperature through a nozzle with a hydroxyaromatic compound to produce aqueous alkali metal sulfide and / or hydrogen sulfide particles having an average particle size of <800 μm, optionally A method for producing polyarylene sulfide, which may be branched. |
