POLYAMIDE RESIN AND HINGED MOLDED ARTICLES

摘要

A polyamide resin comprising components which comprise adipic acid units as dicarboxylic acid units and pentamethylenediamine and hexamethylenediamine units as diamine units, characterized in that the proportion by weight of the pentamethylenediamine units to the hexamethylenediamine units is from 95:5 to 60:40; a vibration-welded molding which is made of the polyamide resin and has excellent vibration-welding strength; a hinged molding and a binding band which have excellent low-temperature toughness; a filament having excellent transparency; and a hinged molding comprising a polyamide resin made up of adipic acid units and pentamethylenediamine units.
