Abstract
Abstract This invention relates to an antistatic additive for polymers, particularly polyurethanes. The additive comprises an ionizable metal salt of a fluoroalkyl sulfonic acid and an enhancer. The enhancer is generally a salt or ester of a carboxylic acid or a phosphate ester. A substantial increase in conductivity or static dissipative properties over that of the organic polymer alone is obtained by incorporating the additive into the polymer composition.
