    摘要： A process for producing an α-olefin oligomer by oligomerization of an α-olefin in a presence of a Ziegler-based catalyst, the process comprising introducing at least a portion of a reaction product which is taken out of a reactor and has a temperature of 115° C. or higher into an external heat exchanger, cooling the introduced reaction product, maintaining an oligomerization solution taken out of the external heat exchanger at a temperature of 110° C. or higher and returning at least a portion of the oligomerization solution to the reactor. In the production of an α-olefin oligomer, precipitation and adhesion of polymers at the inside of manufacturing apparatuses such as the external heat exchanger and troubles caused thereby can be prevented and a stable continuous operation can be continued for a long time.

    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.
