Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention provides a resin molded article having excellent antistatic properties, durability, and impact resistance.
The present invention relates to a thermoplastic resin composition.

[0002]

2. Description of the Related Art Thermoplastic resins such as polyolefin resins, ABS resins, and vinyl chloride resins have been widely used for packaging materials such as films and bags, automobile parts, and the like. Resin generally has a large electric resistance, and has a serious drawback that it is easily charged by friction and sucks dust and the like.

Therefore, in recent years, an antistatic agent has been used as a method for imparting an antistatic property to a thermoplastic resin.
There have been proposed (a) a method of applying an antistatic agent on a resin surface and then drying, and (b) a method of kneading an internal addition type antistatic agent into a resin.

In the above method (a), a surfactant solution is used as an antistatic agent. However, such an antistatic agent is easily removed by washing, and therefore, a permanent antistatic agent is used. There is a drawback that it is not possible to impart the property.

In the method (b), glycerin fatty acid ester, sorbitan fatty acid ester, alkyldiethanolamide, sodium alkylbenzenesulfonate, quaternary salt of alkylimidazole, etc. are used as the internal addition type antistatic agent. When these internal addition type antistatic agents are used, even if the antistatic agent on the surface is lost by washing, a new antistatic agent bleeds sequentially from the inside, so that the antistatic property is improved. Has the advantage of lasting for a relatively long time.

However, when such an internal addition type antistatic agent is used, it takes a long time to recover the antistatic property after washing, and when the antistatic agent bleeds excessively, In addition to the drawback that tackiness occurs and dust and the like are more likely to adhere, since these antistatic agents have low molecular weight, they evaporate due to the heat during molding processing at high temperatures, for example. There is a disadvantage that it is necessary to add more antistatic agent than necessary,
It was difficult to adjust the effective amount.

In order to solve the drawbacks of the above-mentioned internal addition type antistatic agents, in recent years, 20-80 mol% of methoxy groups have been modified with diethanolamine (polyethyl methacrylate) (JP-A-1-170603) and alkoxypolyethylene glycol methacrylate. Polymer (Japanese Patent Publication No. 58-39860), a styrene-maleic anhydride copolymer imide-modified, and then quaternized and cationized (Japanese Patent Publication No. 1-29820), the terminal of which is carboxyl. -Type copolymers of high molecular weight monomers in which the terminal carboxyl groups have been converted to methacryloyl groups with glycidyl methacrylate and aminoalkyl acrylates or acrylamides and their quaternized cation-modified products No. 62-121717 Polymer compounds having antistatic functional groups, such as multi-address) has been proposed. However, all of the above-mentioned polymer compounds have the drawbacks that the physical properties of the resin such as transparency and strength and elongation are deteriorated, and the antistatic property and the durability thereof are insufficient.

In order to solve the above-mentioned drawbacks of the polymer compound having an antistatic functional group, the present inventors have proposed a polyethylene copolymer having a quaternary ammonium salt group-containing acrylamide structural unit. (Japanese Patent Application No. 2-3310
85), even if this copolymer is used, the antistatic effect and its durability, and the strength and elongation when formed into a film are excellent, and although considerable problems have been solved, a molded product is obtained by injection molding or the like. In such a case, mechanical properties such as impact resistance are not sufficiently satisfied, and there is a problem when it is applied to a molded product.
