However, poly-1-butene, like other polyolefins such as polyethylene and polypropylene, cannot be used as is.
Since it does not adhere to polar materials such as metals, concrete, nylon, saponified ethylene/vinyl acetate copolymers, etc., some modification is required to improve adhesiveness. As a method for improving the adhesion between polyolefin and such polar materials, a method using a modified polyolefin in which part or all of the polyolefin is modified with an unsaturated carboxylic acid or a derivative thereof (for example, Japanese Patent Publication No. 49-4
No. 822, Japanese Patent Publication No. 55-49989, Japanese Patent Publication No. 53-36872, etc.) have been proposed and are widely used for laminating polyolefins and polar materials. When this method is applied to poly-1-butene, that is, modified poly-1-butene modified with an unsaturated carboxylic acid anhydride is used as an adhesive for poly-1-butene, the adhesion between poly-1-butene and polar materials is improved. I found out that it will happen. However, as mentioned above, polyl-butene is a polyethylene or polypropylene.

Among the propylene polymers, block copolymers and random copolymers are preferred because they have greater adhesive strength with polar materials and interlayer adhesiveness with poly-1-butene layers than propylene homopolymers, and are particularly preferred for packaging films. Random copolymers are suitable when optical properties such as transparency are required, such as in the field, and fields where adhesive strength and impact strength are especially required when laminating with metals, such as internal or external coatings on steel pipes. A block copolymer is passed through.

In either method, it is necessary to heat at least the modified 1-butene polymer composition to a temperature higher than its melting point before laminating it on the excavable material.

Furthermore, the modified 1-butene polymer composition of the present invention does not necessarily need to be laminated with poly-1-butene, but a powdered composition is used and a preheated polar material is immersed in the fluidized bed to form the polar material. It may be used for powder coating by a fluidized dipping method in which the composition is coated on the surface of the powder or by a thermal spray coating method in which the composition is thermally sprayed using a gas burner.
