ABSTRACT:
An antistatic polyester polyurethane foam containing substantially uniformly incorporated therein as an antistatic material a combination of a particulate, electrically conductive material, such as carbon black, and a haloacetic acid, such as dichloroacetic acid. The combination of conductive material and haloacetic acid which is incorporated into the polyurethane foam during its in situ preparation is believed to be tied into the foam through reaction of the haloacetic acid and at least the diisocyanate used in the foam formulation. The polyurethane foams of this invention have excellent antistatic properties while retaining the desirable features of a good polyurethane foam including uniformity of cell size, no pinholing, and good structural stability.
