Anti-static resin composition containing fluorinated phosphonium sulfonates
First Claim
1. A method for making a molded article comprising a thermoplastic resin composition having enhanced antistatic properties made by the process comprising the steps of adding an effective amount of an antistatic agent to a thermoplastic resin, and mixing together the agent and the thermoplastic resin at the time of polymer production or fabrication of the molded article by molding and molding a molded article from the mixed-together agent and thermoplastic resin, wherein the antistatic agent has the following formula:
-
wherein X is independently selected from the group consisting of bromine, chlorine, fluorine, iodine and hydrogen, provided that at least one X is selected from the group consisting of bromine, chlorine, fluorine and iodine;
n, m and m p are integers from 0 to 12;
with the proviso that when p is an integer from 1-12, Y is zeroa single bond or is selected from the group consisting of nitrogen, oxygen, sulfur, selenium, phosphorus and arsenic, and when p is 0, m is 1 to 12, Y is selected from the group consisting of nitrogen, oxygen, sulfur, selenium, phosphorus and arsenic;
R1, R2 R3 are the same as each other, and are selected from the group consisting of an aliphatic hydrocarbon radical of 1-8 carbon atoms and an aromatic hydrocarbon radical of 6-12 carbon atoms; and
R4 is a hydrocarbon radical of 1-18 carbon atoms.
