摘要： There is disclosed a process for removing volatile components in a polyarylene sulfide resin which is produced by subjecting a sulfur source and a dihalogenated aromatic compound to polymerization reaction in an aprotic organic solvent, comprising using an extruder which is equipped with front vent having an opening length in the range of 4D to 11D (D: screw diameter) and which has a distance between a terminal position of a screw in a kneading portion and the opening portion of the front vent being in the range of 4D to 15D. The process is capable of steadily and economically removing volatile components in the polyarylene sulfide resin without necessitating expensive machinery or equipment such as a dryer without plugging up the opening portion of a vent even in the case of degassing a PAS resin having a low molecular weight and further, thus enabling a long-term continuous stable running.
