鋭意検討した結果、ナイロン４Ｂを主成分とするポリア
ミドからなるコネクターが上記問題を解消できることを
見出し、本発明に至った。(Means and effects for solving the problems) As a result of intensive studies, the present inventors found that a connector made of polyamide containing nylon 4B as a main component can solve the above problems, leading to the present invention.
本発明でいうナイロン４６とはテトラメチレジアミンと

レポリマーを作りこれを更に融点以下の温度で固相重合
する方法がある。Nylon 46 in the present invention is a linear high molecular weight polyamide obtained by polymerizing tetramethylene diamine and adipic acid, and its manufacturing method is, for example, heating tetramethylene diamine and adipic acid in an aqueous solution at 150 to 310 °C. There is a method in which a prepolymer is prepared and then solid-phase polymerized at a temperature below the melting point.
ナイロン４６を主成分とするポリアミドとはナイロン４
６と他のポリアミドとの共重合体もしくはポリマーブレ
ンド物であり、他のポリアミドとじては一般にＴ業的に
作られているポリアミドであればよく特に限定しない。Polyamide whose main component is nylon 46 is nylon 4.
It is a copolymer or polymer blend of No. 6 and other polyamides, and the other polyamides are not particularly limited as long as they are polyamides generally produced by T-manufacturing.
