Process for the preparation of polyarylene sulfide and an apparatus for the preparation thereof. |
摘要 |
<p>High molecular weight polyarylene sulfide is prepared by reacting an alkali metal sulfide with a dihaloaromatic compound in an organic amide solvent, wherein a gaseous phase part of a reactor is cooled to thereby condense a part of a gaseous phase in the reactor, and the condensed liquid is refluxed to a liquid phase in the reactor. Higher molecular weight is attained by copolymerization with 0.005 to 1.5 mole percent, based on the alkali metal sulfide, of a polyhaloaromatic compound. <IMAGE></p> |
