摘要： The present invention provides a method for granulating a polyamide or a polyamide composition, whereby it becomes possible to granulate even a polyamide that has such a melt viscosity that the polyamide cannot be pelletized into a strand-like shape easily. In the present invention, a polyamide, whose melt viscosity at glass transition temperature+160° C. and a shear rate of 100 s−1 is 3 Pa·s to 200 Pa·s and whose terminal amino group concentration is 5 μeq/g to 70 μeq/g, is melted by heating to a range of glass transition temperature+160° C. to glass transition temperature+180° C. of the polyamide, and then is solidified by dropping the molten polyamide in the form of granules onto a metallic belt, thereby producing granules.

摘要： A polyamide resin is produced through polycondensation by melt-kneading a polyamide oligomer having a relative viscosity of from 1.1 to 1.3 and a water content of 3% by mass or less in a cylinder (S) of an extruder. The extruder includes open vents (OV1) and (OV2) and vacuum vents (V1) and (V2). The open vent (OV1) is arranged near a supply port (A3), e.g., above the supply port (A3), and a pressure-decreasing element (Y) is arranged on an upstream side with respect to positions of the vacuum vents (V1) and (V2). In addition, the open vent (OV2) is arranged in a preceding area (OA) and is brought into a pressurized state.
