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 100s -1 is 3Pa·s to 200Pa·s and whose terminal amino group concentration is 5µeq/g to 70µeq/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.
