Method of making a thermoplastic composition containing an antistatic agent |
| abstract |
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) n n nwherein 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 sodium hydroxide and/or lithium hydroxide, a compound of the generic formula (4) n nwherein X, q, p, and r are as defined above, and a compound of the generic formula (3) n n(R) 4 P-Z (3) nwherein Z is a halogen and R is as defined above; and separating the phosphonium sulfonate of formula (1) from the aqueous medium. The phosphonium sulfonate salt is then combined with a thermoplastic resin. |
