Abstract
Provided are a xylylenediamine composition containing xylylenediamine and bis(methylbenzyl)amine, a content of the bis(methylbenzyl)amine being 0.0005 to 0.1 parts by mass based on 100 parts by mass of the xylylenediamine; and a method for producing a polyamide resin including the steps of introducing a diamine containing xylylenediamine, a dicarboxylic acid, and bis(methylbenzyl)amine in an amount of 0.0005 to 0.1 parts by mass based on 100 parts by mass of the xylylenediamine into a reaction system and performing a polycondensation reaction.
