Abstract
An antistatic additive includes a tetrahalogenated ionic compound. An antistatic additive composition for organic polymer compositions includes an antistatically-effective amount of the tetrahalogenated ionic compound, a solvent for the tetrahalogenated ionic compound, and a diluent compatible with the tetrahalogenated ionic compound, the solvent and the organic polymer composition. The tetrahalogenated ionic compound preferably is a tetrahalogenated borate, and more specifically lithium or sodium tetrafluoroborate. Organic polymer compositions containing the additive also are provided, as are methods incorporating the additive into the polymer compositions.
Claims26
An organic polymer composition stabilized against static comprising:

- and X is a halogen.
An organic polymer composition stabilized against static comprising:
- an organic polymer;
- and
- about 0.5% to about 15% by weight of a tetrahalogenated ionic compound of the form AMX4, where A is a salt-forming cation or a salt-forming alkali metal;
- M is an element, or a compound containing an element, the element being selected from Group IIIA of the periodic table;
- and X is a halogen.
An organic polymer composition stabilized against static comprising:
- a polyurethane;
- and
- an antistatically-effective amount of a tetrahalogenated ionic compound of the form AMX4, where A is inorganic, and is a salt-forming cation or a salt-forming alkali metal;
