Abstract:
A substantially transparent, moldable, thermoplastic multipolymer composition comprising:(a) a methyl methacrylate copolymer of a predominant amount of methyl methacrylate and a minor amount of one or more ethylenically unsaturated monomers; and (b) an effective amount of a polyetheresteramide to enhance the electrostatic charge dissipation of the copolymer, said polyetheresteramide having a refractive index within about 0.005 units of the refractive index of the copolymer, such that when the composition is injection molded into a 0.125 inch thick plaque, the plaque exhibits a haze of not greater than about 25% and a light transmission of at least about 60%.
