Abstract
Description
【発明の詳細な説明】 〈産業上の利用分野〉 本発明はポリエステル樹脂組成物に関する。[Detailed description of the invention] <Industrial application field> The present invention relates to polyester resin compositions.
更に詳しくは熱可塑性ポリエステル、ポリアミドおよび
オレフィン・ビニルアルコール共重合体鹸化物から得ら
れるガスバリア性の優れた樹脂組成物に関する。More specifically, the present invention relates to a resin composition with excellent gas barrier properties obtained from a thermoplastic polyester, a polyamide, and a saponified olefin/vinyl alcohol copolymer.
〈従来技術〉
熱可塑性ポリエステルは、剛性、耐衝撃性、耐熱性等に
優れ、毒性がなく衛生面も良好なため、飲料、ｒＡ味科
料容器して広く用いられるに至っている。しかしながら

望まれている。<Prior Art> Thermoplastic polyester has excellent rigidity, impact resistance, heat resistance, etc., is non-toxic, and has good hygiene, so it has come to be widely used as containers for beverages and rA flavorings. However, the permeability of oxygen gas and carbon dioxide gas is not necessarily satisfactory, and further improvements are desired as containers for foods and the like.

器については、この改質手段はなお不充分であった。As a means of improving gas barrier properties, a method has been proposed, for example, of mixing a polyester resin with a resin that has better gas barrier properties than polyester resin, but at present it is not always possible to obtain a satisfactory molded product. The reason for this is
Ethylene-vinyl alcohol copolymer can be mentioned as a resin with excellent gas barrier properties. Although polyester resin containing this ethylene-vinyl alcohol copolymer certainly has excellent gas barrier properties under low humidity conditions, it At lower temperatures, the gas barrier properties are reduced to almost that of the polyester resin alone, so this modification method is still insufficient for containers that require long-term storage.
