FIELD: chemistry.
SUBSTANCE: invention relates to a xylylenediamine composition useful as a starting material for the preparation of a polyamide resin and to a process for producing a polyamide resin, which can be used for the production of packaging films, hollow containers, various molding materials, fibers, etc. Method for producing a polyamide resin is that a xylylenediamine composition containing xylylenediamine and bis-(methylbenzyl)amine and a dicarboxylic acid is introduced into the reaction system. Polycondensation reaction is then carried out. Content of bis-(methylbenzyl)amine is from 0.0005 to 0.1 parts by weight per 100 parts by weight of xylylenediamine.
EFFECT: invention makes it possible to obtain a polyamide resin that is less dyed, rapidly crystallizes and has excellent transparency.
