Abstract:
A water reaction synthesis with polyoxyethylene diol, diisocyanate and dibutyltin bis lauryl mercaptide produces a high molecular weight thermoplastic polyurethane-urea linear polymer with surface resistivity 10.sup.11 -10.sup.6 ohm/sq. Thermoplastic and/or elastomeric antistatic compositions containing other melt processable polymers and/or filler, and the polymer exhibit permanent protection. Antistatic protection can be increased when the polymer complexes with a metal salt such as lithium chloride, or lithium acetate.
