PURPOSE:The titled composition useful as various kinds of ornaments, signboards, illuminators, etc., having improved permanent antistatic properties, obtained by blending a copolymer of acrylic monomers consisting of methyl methacrylate as a main component and a specific sulfonate with a specified alkylene oxide compound, etc. in a specific ratio. CONSTITUTION:(A) A copolymer of (i) 100pts.wt. acrylic monomers consisting of methyl methacrylate as a main component and (ii) 0.5-15pts.wt. sulfonate shown by the formula I or formula II (R' is 1-18C hydrocarbon; R<2> is H, or methyl; X is 2-4C alkylene oxide; m and n are 0-35; M is alkali metal, ammonium, organic amine salt, or organic quaternary ammonium salt) is blended with (B) 0.3-15pts.wt. alkylene oxide compound shown by the formula R<3>O-(Y)l-R<4> (R<3> is H, hydrocarbon, acryloyl, etc.; R<4> is H, 1-18C alkyl, allyl, aryl, etc.; X is 2-4C alkylene oxide; l is 1-35) and (C) 0-5pts.wt. acidic phosphoric ester, to give the desired composition.
