POLYAMIDE RESIN COMPOSITION

摘要

a polyamide (X) having a diamine constituent unit which mainly comprises a metaxylylenediamine unit and a dicarboxylate constituent unit which mainly comprises an adipate constituent unit; and specific amounts of a phosphate-type antioxidant and alkaline component. The polyamide (X) is characterized by a specific terminal group concentration balance and a specific amino group reaction rate. By using the polyamide resin composition, both of the prevention of yellow discoloration and the reduction of gelatinization or fisheye formation can be achieved.
