Abstract: An antistatic composition contains an ambient-temperature molten lithium salt dihydrate, and one of a polymerizable compound, a plastic resin, an elastomer and an adhesive resin in which the lithium salt dihydrate is dispersed. The lithium salt dihydrate contains two types of lithium salts with different molecular weights from each other. The two types of the lithium salts are selected from a group of lithium salts each containing an anion having a fluoro group and a sulfonyl group.

Abstract: An antistatic composition that is excellent in thermo stability, is free from the problem of bleeding-out, exhibits its effect independently of humidity, has immediate effectiveness, and also exhibits excellent and persistent antistatic properties, and a method for producing the composition are provided. The antistatic composition comprises a predetermined alkali metal salt or alkaline earth metal salt, and resin.
Abstract: The present invention relates to a microwave chemical reaction apparatus characterized by comprising a means for heating a reaction liquid, which is capable of irradiating microwaves while controlling the output power according to the temperature of the reaction liquid, together with a means for forcibly cooling the reaction liquid from the outside, and being capable of precisely controlling the reaction temperature. The microwave chemical reaction apparatus can control the reaction temperature precisely, for example, within ±1° C. of a predetermined temperature, and can be applied to fine chemical reactions. Further, since reactions proceed rapidly in such an apparatus, mass production can be achieved by a relatively small-sized reaction apparatus.

Abstract: The present invention provides a polymeric-type antistatic agent containing a polymer composition consisting of a polymeric-type antistatic agent containing a resin or/and an elastomer as a main component thereof; or/and a thermoplastic resin having a polar group or/and an elastomer having the polar group. At least one kind of an anion-containing salt, having a fluoro group and a sulfonyl group, is added to the polymer composition without intermediary of a medium consisting of a low-molecular-weight polyether-containing compound or a low-molecular-weight polar compound whose number-average molecular weight is not more than 5000. The present invention also provides a composition, for a conductive roller or the like, containing polymer components and the polymeric-type antistatic agent dispersed in the polymer components.
