  • Patent number: 8742017
    Abstract: There is provided an antistatic agent that preserves its antistatic property for a long period of time and has the appearance and the transparency that are not impaired when kneaded into a resin, and a resin composition containing the antistatic agent. An antistatic agent including a block copolymer which is obtained from a reaction product of a polyolefin (a) having one end being acid-modified and a diol and/or a diamine (b) having a polyoxyalkylene chain, and in which a part or all of acid groups remaining in the reaction product is neutralized with an alkaline substance. A thermoplastic resin composition including the antistatic resin. A film or sheet including the thermoplastic resin composition.

  • Publication number: 20130123434
    Abstract: There is provided as an antistatic agent that preserves antistatic properties for a long period of time and that does not impair the appearance and transparency of a resin into which the antistatic agent is kneaded, and a resin composition containing the antistatic agent. A block copolymer obtained from a reactant between (a) an acid-modified polyolefin and (b) an alkylene oxide adduct of amide alcohol of General Formula (1), part or all of residual acid groups in the reactant being neutralized by an alkaline substance: R1—CONH—R2—O-(A1O)n-H (1) (where R1 is a C1-21 linear or branched alkyl group or alkenyl group; R2 is a C1-4 linear or branched alkylene group; A1 is a C2-4 alkylene group; and n is an integer of 1 to 100); an antistatic agent including the block copolymer; a thermoplastic resin composition including the antistatic agent; and a film or sheet including the composition.
