Abstract

To provide a polyamide resin composition containing an added crystal nucleator suitable for promoting the crystallization of a polyamide resin and not triggering discoloration in the resin, the polyamide resin composition being capable of raising the crystallization rate and achieving better molding process properties and heat resistance in comparison with the polyamide resin. A polyamide resin composition including a polyamide resin and a crystal nucleator comprising a carboxylic acid derivative represented by formula [1]. B1-L1-A-L2-B2 [1] (In the formula, A represents an optionally substituted C1-6 alkylene group or C6-10 divalent aromatic group, B1 and B2 represent optionally substituted C3-6 cycloalkyl groups or optionally substituted C6-10 aromatic groups, and L1 and L2 represent -C(=O)NR1- or -C(=O)O-.).

Description

technical field

[0001] The present invention relates to a polyamide resin composition, and more specifically, to a polyamide resin composition containing a crystal nucleating agent composed of a carboxylic acid derivative, and a polyamide resin molded article obtained from the resin composition. Background technique

[0002] Polyamide resins are generally widely used as engineering plastics excellent in mechanical properties, chemical resistance, oil resistance, and the like. Among them, polyamide 11 and polyamide 12 are excellent in properties such as chemical resistance, impact resistance, cold impact resistance, and low water absorption, and thus are expected to be used as, for example, food containers, bearings, connectors, fuel pipes for automobiles (tube) / Molding materials for hoses, interior materials, housings and components of electrical / electronic products.

[0003] However, polyamide resins have a disadvantage that, since the crystallization rate is slow, soften...
