ABSTRACT:
An electrically conductive polyurethane elastomer obtained by the reaction of a polytetramethylene ether glycol having the formula HO[(CH.sub.2).sub.4 O].sub.x H where x is from 8 to 41 and from about 20 to about 95 parts by weight per 100 parts by weight of the glycol of at least one diisocyanate, a sufficient amount of cross linking agents and chain extenders to provide a crosslinked elastomer and an amount of an asymmetric ionic quarternary ammonium salt having the formula: ##STR1## Where R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are C.sub.n H.sub.2n+1 and 1.ltoreq.n.ltoreq.25 sufficient to provide a resistivity of from about 10.sup.7 to about 10.sup.11 ohm cm. In a preferred embodiment the asymmetric ionic quarternary ammonium salt is (3-lauramidopropyl) trimethylammonium sulfate.
