Claims5
An antistatic composition consisting of:
- (a) at least one antistatic agent consisting of:
- (i) at least one anion represented by one of the following formulae:
- wherein each Rf is independently a fluorinated alkyl or aryl group that may be cyclic or acyclic, saturated or unsaturated, and may optionally contain catenated or terminal heteroatoms selected from the group consisting of N, O, and S;
- Q is independently an SO2 or a CO linking group;
- and X is selected from the group consisting of QRf, CN, halogen, H, alkyl, aryl, Q-alkyl, and Q-aryl;
- where any two contiguous Rf groups may be linked to form a ring;
- and
- (ii) at least one cation having at least one polyoxyalkylene moiety bonded to at least one cationic nitrogen center;
- and
- (b) at least one insulating material.
