Abstract
An antistatic resinours composition comprising (A) graft copolymers prepared by emulsion polymerization of (a) monomer mixture consisting of (i) from 50 to 100 percents by weight of monomers having polyalkylene oxide chains and (ii) from 50 to 0 percents by weight of vinyl monomers in the presence of rubbers and (B) thermoplastic resins compatible with the graft copolymers, has permanent antistatic performances, superior mechanical properties and high flowability.
