    摘要： The fuel-barrier polyamide resin of the present invention is a product of the polycondensation of a diamine component comprising 70 mol % or higher of m-xylylenediamine and a dicarboxylic acid component comprising 70 mol % or higher of a mixed dicarboxylic acid which comprises a C4 to C20 α,ω-linear aliphatic dicarboxylic acid and at least one dicarboxylic acid selected from the group consisting of isophthalic acid and naphthalenedicarboxylic acid in a molar ratio of 30:70 to 95:5. The polyamide resin is excellent in not only fuel-barrier property and heat resistance, but also moldability and recyclability, and therefore suitably used as a barrier material of fuel containers.

    摘要： There is provided a multilayer bottle comprising a barrel portion including an outermost layer, an innermost layer and at least one barrier layer interposed between the outermost layer and the innermost layer, which satisfies the requirements represented by the following formulae (1) to (3) at the same time: OTR≦0.2 cc·mm/(m2·day·atm)  (1) where OTR represents an average oxygen transmission rate of the barrier layer of the barrel portion; 20≦(Average degree of orientation of barrier layer of barrel portion)≦45; and  (2) 0≦b/a≦100≦200  (3) where “a” represents an average thickness (μm) of the barrier layer of the barrel portion; and “b” represents an average thickness (μm) of the barrier layer of a bottom portion of the bottle. The multilayer bottle is free from delamination owing to impact upon dropping even when the bottle is formed with irregularities and bends and therefore exhibits a large freedom of design choice.

    摘要： There is provided a multilayer bottle including an outermost layer and an innermost layer which are each made of a thermoplastic polyester resin, and at least one barrier layer interposed between the outermost layer and the innermost layer. The barrier layer contains at least two components including a polyamide obtained by polycondensing a diamine component containing m-xylylenediamine as a main component with a dicarboxylic acid component containing an α,ω-linear aliphatic dicarboxylic acid as a main component, and a thermoplastic resin having a lower molecular weight than that of the polyamide. The multilayer bottle hardly suffers from delamination upon impact or dropping and, therefore, is not required to have a shape with less irregularities or less bends for preventing the delamination, and further has a large freedom of design choice.

    摘要： The thermoplastic resin composition of the invention comprises (A) 50 to 97% by weight of a polyolefin, (B) 2 to 45% by weight of a polyamide resin comprising a diamine component and a dicarboxylic acid component and (C) 1 to 45% by weight of a modified polyolefin and/or styrene copolymer. The polyamide resin is specified by that at least 70 mol % of the diamine component is a constitutional unit derived from m-xylylenediamine and at least 70 mol % of the dicarboxylic acid component is a constitutional unit derived from a C4-C20 straight-chain α,ω-aliphatic dicarboxylic acid and isophthalic acid in a molar ratio of 3:7 to 10:0. With such a chemical component, the thermoplastic resin composition exhibits excellent fuel barrier properties, heat resistance and moldability.
