A method is provided for recovering poly(arylene sulfide) from a mixture comprising a liquid-phase poly(arylene sulfide) and a polar organic compound, wherein the liquid mixture is contacted by an amount of a liquid, vaporized, or mixed phase separation agent at least sufficient to effect or enhance a phase separation of the liquid-phase poly(arylene sulfide) component from the polar organic compound. The poly(arylene sulfide) resins recovered according to this invention generally exhibit uniform particle size and do not tend to adhere to vessel walls during the recovery.
本发明提供了一种从由液相聚芳基硫醚和极性有机化合物组成的混合物中回收聚(芳基硫醚)的方法,其中液相混合物与一定量的液相、气化相或混合相分离剂接触,该量至少足以实现或加强液相聚(芳基硫醚)组分与极性有机化合物的相分离。根据本发明回收的聚(芳基硫醚)树脂一般粒度均匀,在回收过程中不会粘附在容器壁上。
