Process for granulating polyarylene sulfide based-resin

Abstract

There is disclosed a process for granulating a polyarylene sulfide-based resin which comprises extruding a molten polyarylene sulfide-based resin with an extruder through a die nozzle, thereafter taking off the resin in cooling water at a temperature in the range of 5 to 60° C. which flows down on a prescribed inclined surface, and cutting off the resin and pelletizing the same at a prescribed position on the downstream region. It is made possible by the above process to efficiently steadily produce micro-pellets and amorphous pellets of the polyarylene sulfide-based resin. Furthermore, in the case of preparing the compound of the pellets by compositing with a filler such as calcium carbonate, the stability of an extruder can be assured by the specific resin pellets.
