Synthetic resins have excellent insulating properties, and this property is utilized, but once charged, they have low conductivity and are difficult to leak, causing various static electricity problems, which has become a problem. In other words, dust adhesion due to electrostatic charge occurs during molding or after processing, which poses a troublesome problem in distribution and use, and causes accidents such as fires and injuries due to electric shock caused by charged static electricity. It also becomes the source of errors in instruments. There is a strong desire to solve these problems. Furthermore, recently, when resins are used as substrates for electronic devices, the problem of dust adhesion due to charging has become severe, and there has been a growing demand for prevention of charging.

In addition, surface processing such as painting or plating on the surface of plastics has been increasing recently, and the static electricity generated in such cases has an impact on the surface processing, and as the processing process speeds up, There is a growing demand for antistatic properties even during the short time between molding and subsequent processing.

In response to the above situation, there are many proposals regarding permanent antistatic agents, but there are very few kneaded-in types that are effective immediately after molding, and even if they are effective, the degree of effectiveness is extremely low. Conventional permanent antistatic agents show some effect after molding, but this varies depending on the type of resin.
The level of effectiveness of the antistatic agent is reached after 2 to 3 days at the earliest, and the effectiveness is maintained for 1 to 2 years or several years thereafter. Various compounds have been reported as antistatic agents that exhibit such effects. As an antistatic agent for polyolefins, a mixture of β-hydroxyalkyl-N-hydroxylamine obtained by the reaction of an olefin oxide and an alkanolamine is known (Tokuko Sho 3L).
-57561), although it has a permanent antistatic ability, it is not effective immediately after molding (it takes several days for the effect to appear, and it cannot be processed immediately after molding as mentioned above). Furthermore, it is not suitable when β-hydroxyalkyl-N
- A mixture of ethanolamine and N,N-di(β-hydroxyalkyl)-N-ethanolamine is used as an antistatic agent for ABS resin (Japanese Patent Publication No. 50-14'261) and polystyrene resin (Japanese Patent Publication No. 51-7499). Patents have been applied for, but these also have a permanent effect, but
The effect immediately after molding is low, and it is difficult to apply it to the above-mentioned uses. The latter two are β-hydroxyalkyl-
It is said that a mixture of N-ethanolamine and N1N-di(β-hydroxyalkyl)-N-ethanolamine is more effective than β-hydroxyalkyl-N-ethanolamine alone, but β-hydroxyalkyl-N-ethanolamine The higher the effect is, the greater the amount of the compound alone or the higher the content thereof, so the level of effect is low and the permanent effect is not sufficient.

In addition, these antistatic agents have the disadvantage that, when washed repeatedly with water to check durability and recovery of the effect, the recovery of the effect is slow, and the effect decreases with the number of washings.

As mentioned above, most of the reports that have been reported so far are intended to have a permanent antistatic effect, and are not intended to be effective immediately after molding and have a permanent effect. These durability effects are also of a low level and do not have a high antistatic effect over a long period of time. In addition, many compounds and compositions are considered to have immediate effects, but these have only temporary effects but are not long-lasting (and some are not permanent antistatic agents). It is impossible to mix them, or they have drawbacks such as warping and reducing the effectiveness.

The present invention was devised focusing on these points, and the effect begins to appear within a few hours after molding and kneading, and a high level of effect is achieved within a day, and the effect is permanent.

The reaction product of 12-epoxyalkane and monoethanolamine is obtained by reacting 21 moles of 12-epoxyalkane with 1 to 6 moles of monoethanolamine. This reaction is carried out using the above raw materials in a reactor under an inert gas at 110 to 15
This is done by heating at 0°C. The reaction product obtained here is a compound obtained by the addition reaction of one molecule of 1,2-epoxyalkane to one active hydrogen in a monoethanolamine molecule (hereinafter referred to as "1-1 addition"). (hereinafter referred to as "2-1 adduct") and a compound obtained by reacting two active hydrogen molecules in a monoethanolamine molecule with two molecules of 1,2-epoxyalkane (hereinafter referred to as "2-1 adduct"). It is a mixture, and the mixing ratio is 11-1 adduct J: r by weight ratio.
The 2-1 adduct and J-10:0 to 7:3 are good, and it is preferable to use as much of the "1-1 adduct" as possible because it is more effective.

The mixing ratio of "1-1 adduct" and "12-1 adduct" is determined by measuring the total amine value, partial amine value, and tertiary amine value, and the theoretical molecular weight of the tertiary amine compound (r2-1 adduct). I wonder. The reaction product (B) is obtained by reacting a fatty acid having an alkyl group or an alkenyl group having 7 to 21 carbon atoms with aminoethylethanolamine.
