Title:
RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP3674650
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a resin composition having improved gas barrier properties, as it holds excellent transparency and resistance to chemicals, by mixing polyethylene terephthalate with a xylylene group-bearing polyamide.
SOLUTION: A mixture of 70-98wt.% of polyethylene terephthalate and 30-2wt.% of a xylylene group-bearing polyamide is melt-kneaded to give the objective resin composition wherein the concentration of the terminal amino groups (a) (μ equivalent/g) and that of the terminal carboxyl group (b) (μ equivalent/g) of the xylylene group-bearing polyamide satisfy both of the following conditions (1) and (2) before the melt kneading: (1) 50≤a-b≤300 and (2) a+b≤300.
