Abstract: It is to provide an antistatic material that can maintain a high degree of electrostatic charge quenching performance over a long period without using an internally kneaded type antistatic agent, a method for manufacturing the same, and a method for preventing electrification using the same. An antistatic material of the present invention is that comprising an acrylic resin which is obtained by copolymerization of an acrylic monomer as an essential component including 70% by weight or more of methyl methacrylate and have in a main chain a structural unit of the following formula (1) having a side chain including a donor-acceptor molecular compound type atomic group consisting of non-ionic pair, in a proportion of 0.5 to 5% by weight based on a whole resin.

Abstract: An object of the present invention is to provide an antistatic agent composed of a donor-acceptor type molecular compound that can prevent static charge on an insulating polymer material surely with good persistency and reproducibility. The antistatic agent of the present invention is an antistatic agent for an insulating polymer material composed of a donor-acceptor type molecular compound represented by the general formula (1) below and obtained by mixing, melting and reacting a semi-polar organoboron compound (donor component) of the upper part in the general formula (1) below with a basic nitrogen compound (acceptor component) of the lower part in the general formula (1) below, wherein R1 and R2 are each independently CH3(CH2)16—CO—OCH2 or HOCH2 and at least one thereof is CH3(CH2)16—CO—OCH2; R3 and R4 are each independently CH3, C2H5, HOCH2, HOC2H4, or HOCH2CH(CH3); and R5 is C2H4 or C3H6.

Abstract: In welding of metals, spatter preventing effect can be enhanced by spreading on the metal surface a halogen-containing duodimensional polymer having a proper degree of affinity for metals and other materials, being thermoplastic and also having a restoring force and flame resistance as a pretreatment.

Abstract: Cationic surface active agents in which nitrogen atoms are attached to both ends of a long-chain alkylene group or polyoxyalkylene group having at least 6-24 carbon atoms in the molecule, at least one of said nitrogen atoms constituting a quaternary ammonium structure, have also at least one hydroxyphenethyl group bonded to at least one of the two nitrogen atoms. These cationic surface active agents can serve as an accelerator which catalytically promotes changes in a chemical and/or physical change process involving a hydrolyzing, deacidizing or extracting operation using an aqueous solution of an alkaline metal hydroxide or an alkaline earth metal hydroxide.
