Document Type and Number:
WIPO Patent Application WO/2018/180401
Kind Code:
A1
Abstract:
Provided is a resin composition, a molded article, a film, and a multilayer film, which have excellent oxygen barrier properties and transparency, and a high tensile elongation at break. The resin composition contains 80-20 parts by mass of a polyamide resin (B) with respect to 20-80 parts by mass of a polyamide resin (A), wherein a constitutional unit having a C2-6 alkylene chain constitutes more than 35 mole% of all the constitutional units of the polyamide resin (A), and the polyamide resin (B) is composed of a diamine-derived constitutional unit and a dicarboxylic acid-derived constitutional unit, 70 mole% or more of the diamine-derived constitutional unit being derived from xylylenediamine, 30-70 mole% of the dicarboxylic acid-derived constitutional unit being derived from C4-8 α, ω-linear aliphatic dicarboxylic acid, and the remaining 70-30 mole% of the dicarboxylic acid-derived constitutional unit being derived from isophthalic acid (total amount does not exceed 100 mole%). In addition, the resin composition contains 3-300 mass ppm of phosphorous atoms, and contains calcium atoms in a ratio at which the molar ratio of phosphorus atoms:calcium atoms is 1:0.3-0.7.
