Title:
MULTILAYER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2015/022818
Kind Code:
A1
Abstract:
This multilayer structure comprises polyamide resin layers (A) and (B). The layer (A) is configured from a polyamide resin (A1), which contains a constituent unit derived from a lactam having 10-12 carbon atoms and/or a constituent unit derived from an aminocarboxylic acid having 10-12 carbon atoms, or a composition (a) that contains the resin (A1). The layer (B) is configured from a composition (b) that contains a polyamide resin (B1), wherein a diamine unit contains 70% by mole or more of a constituent unit derived from a meta-xylylenediamine and a dicarboxylic acid unit contains 70% by mole or more of a constituent unit derived from an aliphatic dicarboxylic acid having 4-8 carbon atoms, and a polyamide resin (B2), wherein a diamine unit contains 70% by mole or more of a constituent unit derived from a xylylenediamine and a dicarboxylic acid unit contains 70% by mole or more of a constituent unit derived from an aliphatic dicarboxylic acid having 9-12 carbon atoms. The mass ratio (B1/B2) is from 55/45 to 85/15.
