Title:

POLYAMIDE RESIN HAVING EXCELLENT ETHANOL RESISTANCE AND FUEL BARRIER PROPERTY, AND CONTAINER

Document Type and Number:

Japanese Patent JP2011032411

Kind Code:

A

Abstract:

To provide a polyamide resin having excellent ethanol resistance and fuel barrier property, and to provide a multilayered container and a container using the polyamide resin.

The polyamide resin includes a polyamide obtained by polycondensing a diamine component containing ≥70 mol% of meta-xylylene diamine and a dicarboxylic acid component as the main component as a main component. The dicarboxylic acid component is a mixture of a 4-12C α, ω-linear aliphatic dicarboxylic acid and an aromatic dicarboxylic acid regulated so that the percentage of the number of carbons derived from the aromatic ring in the dicarboxylic acid component based on the whole number of the carbons in the dicarboxylic acid component may be 5-25%, and the crystallinity calculated by the measurement of differential scanning calory of the polyamide resin may be ≥5%. The multilayered container and the container are obtained by using the polyamide resin.
