Conventionally, various resins have been used in many fields, but the resin surface is often hydrophobic and easily charged. For example,
Molded articles made from polyolefin-based resins such as polyethylene and polypropylene have a hydrophobic and easily charged surface, reflecting their original low surface tension. Making such a hydrophobic and easily charged resin surface hydrophilic is an essential technique when the resin is applied to various applications in which a hydrophilic surface is required.

Several techniques have been conventionally proposed for this hydrophilization treatment, for example, a method of coating a surface of a resin with a surfactant or a method of kneading this into the resin itself. Among them, the method of applying the surface is effective for temporarily making hydrophilic, but since the treating agent such as a surfactant is easily removed, the effect of sustaining hydrophilicity is small. The kneading method requires a considerably large amount of processing agent to be mixed in order to achieve sufficient hydrophilicity, and there are problems such as insufficient mixing, bleeding of the processing agent from the molded product, and the machine of the molded product. It is easy to cause deterioration of the physical properties and coloring.

On the other hand, the polymerizable surface-coat type treating agent overcomes these problems, but when applied to the surface of, for example, a polyolefin resin, its adhesive strength is insufficient. Further, as the polymerizable surface treating agent, one having excellent alkali resistance has not yet been proposed. Alkali resistance is a particularly important characteristic in applications where it is used in contact with a concentrated alkaline solution, such as a diaphragm for a battery. Traditionally, nylon resin nonwoven fabrics have been used for this type of application,
This product is excellent in hydrophilicity but lacks alkali resistance and long-term stability. For this reason, polypropylene-based resins are gradually being replaced by nonwoven fabrics, but polypropylene-based resins lack hydrophilicity. Therefore, from these circumstances, there is a strong demand for a surface treatment agent which is excellent in alkali resistance and has a large hydrophilic effect.

The alkenylamine (co) polymer in the present invention is a polyamine which has been well known in the prior art, such as an amino group-containing acrylic acid derivative polymer, which does not undergo an alkali bond or an amide bond which is easily hydrolyzed by an alkali, and an amino group and a carbon atom. -It is bonded to the carbon-bonded polymer main chain and has strong alkali resistance. The alkali-resistant hydrophilic surface is effective, for example, as the surface of the battery diaphragm, and the hydrophilicity of the diaphragm allows the liquid retaining property and electric conductivity of the battery to be kept high.
