とするもので、弾性の点で劣るものであった。[Prior Art] Polyether block amide resin is an excellent copolymer resin that can be freely changed in flexibility and various properties by changing the ratio of the nylon component and the polyether component in the composition, It is used in various fields by taking advantage of this excellent feature. However, since it has poor flame retardancy, it has been difficult to apply it to fields requiring flame retardancy, such as automobiles, wire coatings, and tubes. At present, flame-retardant resins compatible with this field are mainly composed of polyvinyl chloride and polyethylene, and have poor elasticity.

性や柔軟性が損なわれる欠点があった。As an attempt to make the polyether block amide resin flame-retardant, it is common to add flame retardants used for polyamide, polyester, etc., for example, melamine-based, cyanuric acid-based, bromine-based or antimony-based flame retardants. However, all of them have a drawback that the flame-retardant effect is small, or even if the flame-retardant property is obtained, the elasticity and flexibility of the polyether block amide resin are impaired.
