本発明は、ポリアミド樹脂本来の優れた耐薬品性に加え

脂製中空ブロー容器を提供するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a hollow blow container made of polyamide resin that has high gas barrier properties and good impact properties in addition to the excellent chemical resistance inherent to polyamide resin. It is.
ポリアミド樹脂製ブロー容器は、耐薬品性と機械的特性

しかしながら、ポリアミド樹脂はプロー成形性に劣り、

配合することが試みられている。Blow containers made of polyamide resin have excellent chemical resistance and mechanical properties, and are widely used as containers for storing various chemicals, oils, solvents, etc.0 However, polyamide resin has poor blow moldability,
In addition, since the impact resistance as a container is poor, attempts have been made to blend, for example, ionomer resin or nitrile rubber (Jikikai R3-IOTO Hiroshi).

従って、ガスバリア性が高く、衝撃特性に優実状であっ
た。However, when nitrile rubber is blended, thermal deterioration during blow molding becomes significant, and when olefin copolymers such as ionomer resins are blended, gas permeability is significantly reduced. It had high strength and excellent impact properties.
本発明者らは、上記問題を解決すべく鋭意研究を重ねた
結果、エチレン・アクリル酸エステル共重合体を配合し

ことを見出し、本発明に到達したものである。As a result of intensive research aimed at solving the above problems, the present inventors found that by using a polyamide resin blended with an ethylene/acrylic acid ester copolymer, blow moldability was significantly improved and gas barrier properties were also maintained. I found out what I can do. Furthermore, even if a copolymer of ethylene and acrylic ester is blended with polyamide, the impact resistance of ordinary injection molded products will not be improved (Tokukosho≠r-/7
&i! : ! ; Comparative Example-j, etc.) and blow-molded product examples, it was surprisingly found that there was a remarkable effect of improving impact properties, and the present invention was achieved based on this finding.
