<p>Herein are disclosed charge-control agents for polyurethane elastomers having the formula: <CHEM> R<2> represents oxyphenylene sulfonate, oxycyclohexylene sulfonate, or p-toluenesulfonamidosulfonyl; R<3> represents a straight or branched chain alkylene group having 2 to 7 carbon atoms; R<4> is the same as R<3> or is -(-R<5>-O-) @R<5>; R<5> is the same as R<3>; M represents hydrogen, an alkali metal, ammonium or P<+>(C6H5)3CH3 and m, n and x are integers which together are of sufficient value to achieve an R<1> molecular weight of 300 to 30,000. The elastomers are useful in making shaped articles.</p> |
