Document Type and Number:
WIPO Patent Application WO/2012/005204
Kind Code:
A1
Abstract:
Disclosed is a polyamide resin composition that has a high elastic modulus, favorable gas barrier properties, low water absorption, and excellent flexibility and transparency. The polyamide resin composition is characterized by containing 1-40 masses of at least one copolymer polyamide (B) selected from the group consisting of the belowmentioned B-1 to B-3 for every 100 masses of a polyamide resin (A) of which at least 70 mol% of the diamine constituent units are derived from xylenediamine, and at least 50 mol% of the dicarboxylic acid constituent units are derived from sebacic acid. (B-1): Copolymer polyamide 6/66/12. (B-2) Copolymer polyamide 6/66/11. (B-3) Polyether copolymer polyamide configured from polyamide 12 units or polyamide 11 units, and polyether units.
