    摘要： A method for preparing a thermoplastic composition containing an antistatic agent is described. The antistatic agent is a phosphonium sulfonate salt of generic formula (1) wherein each X is independently a halogen or hydrogen, provided that the molar ratio of halogen to hydrogen is greater than about 0.90; p is 0 or 1 and q and r are integers of 0 to about 7 provided that q+r is less than 8 and that if p is not zero then r is greater than zero; and each R is the same or different hydrocarbon radical containing 1 to about 18 carbon atoms. The phosphonium sulfonate salt is prepared by a method that includes combining in an aqueous medium a compound of generic formula (2) wherein M is Li or Na, and X, q, p, and r are as defined above, with a stoichiometric excess of a compound of the generic formula (3) (R)4P-Z  (3) wherein Z is a halogen and R is as defined above; and separating the product of formula (1) from the medium. The phosphonium sulfonate salt is then combined with a thermoplastic resin.
