    • 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.
    • 描述了制备含有抗静电剂的热塑性组合物的方法。 抗静电剂是通式(1)的鏻磺酸盐,其中每个X独立地是卤素或氢,条件是卤素与氢的摩尔比大于约0.90; p为0或1,q和r为0至约7的整数,条件是q + r小于8,如果p不为零,则r大于零; 并且每个R是含有1至约18个碳原子的相同或不同的烃基。 鏻磺酸盐的制备方法包括在水性介质中将通式(2)的化合物(其中M为Li或Na,X,q,p和r如上定义)与化学计量过量的 通式(3)的化合物<?in-line-formula description =“In-line Formulas”end =“lead”?(R)4 PZ(3) line-formula description =“In-line Formulas”end =“tail”?>其中Z是卤素,R如上定义; 和将式(1)的产物与介质分离。 然后将鏻磺酸盐与热塑性树脂组合。
