PROCESS FOR PREPARING POLYARYLETHERS

摘要

Process for the preparation of a polymer composition comprising at least one aromatic or a mixture thereof, the process comprising: i) obtaining a reaction mixture comprising polymer precursors in a first fluid boiling in excess of 100 DEG C; ii) subjecting the reaction mixture to a first elevated temperature in excess of 100 DEG C to generate the alkali metal salts of polymer precursors and the polymer reaction products thereof; and iii) subjecting the reaction product mixture to at least a second temperature and isolating the reaction product in the form of a polymer composition which is substantially insoluble in a second fluid, from the first fluid which is substantially soluble in the second fluid, by contacting with an amount of second fluid; wherein the process is conducted in substantial absence of an effective amount of an azeotrope; novel intermediates thereof; polymer composition obtained thereby; resin formulations thereof; method for manufacture of composites thereof; and uses thereof.
