    摘要： The polyamide resin shaped article of the present invention is produced by preliminarily melt-kneading a m-xylylene-containing polyamide resin and a layered silicate subjected to a swelling treatment to prepare a resin composition containing the layered silicate in high concentration, melt-kneading the resin composition with another portion of m-xylylene-containing polyamide resin, and then formed into the shaped article. Since the amount of the m-xylylene-containing polyamide resin exposed to the heat history twice in the melt-kneading steps is minimized, the gel formation due to the thermal degradation can be reduced and the lowering of the relative viscosity due to the decrease of the molecular weight caused by the thermal degradation of the m-xylylene-containing polyamide resin is prevented.

    摘要： In the process of the present invention, a polyamide A1 and an organized clay B are mixed mainly by dispersive mixing, and after added with a polyamide A2, mixed mainly by distributive mixing in a corotating intermeshing twin-screw extruder so designed as to effect the dispersive mixing and the distributive mixing. The organized clay B is completely and finely dispersed and distributed throughout the resultant polyamide composite material. Shaped articles such as films and sheets made of the polyamide composite material exhibit excellent gas barrier properties and transparency with little malodor mainly attributable to the decomposed products of the organizing agent for preparing the organized clay B.

    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： There is provided a multilayer bottle including outermost and innermost layers each made mainly of a polyester (A) and at least one barrier layer interposed between the outermost and innermost layers. The polyester (A) is a thermoplastic resin obtained by polymerizing a dicarboxylic acid component containing 80 mol % or more of terephthalic acid with a diol component containing 80 mol % or more of ethylene glycol. The barrier layer is composed of a polyamide (B) and a polyamide (C). The polyamide (B) is obtained by polycondensing a diamine component containing 70 mol % or more of m-xylylenediamine with a dicarboxylic acid component containing 70 mol % or more of an α,ω-linear aliphatic dicarboxylic acid having 4 to 20 carbon atoms. The polyamide (C) has a higher saturation water content than that of the polyamide (B) as measured at 23° C. and 50% RH under 1 atm, and a content of the polyamide (C) in the barrier layer is 20% by weight or less on the basis of a weight of the barrier layer. The multilayer bottle hardly suffers from delamination upon dropping or upon exposure to impact 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.
