Method of making a thermoplastic composition containing an antistatic agent

摘要

A method for preparing a thermoplastic composition containing an antistatic agent is described. The antistatic agent is a phosphonium sulfonate salt that is prepared by a method that includes combining in an aqueous medium sodium hydroxide and/or lithium hydroxide, a sulfonyl fluoride compound, and a phosphonium halide compound; and separating the phosphonium sulfonate from the aqueous medium. The phosphonium sulfonate salt is then combined with a thermoplastic resin.
