Abstract: The present invention is directed to antistatic elastomeric articles and methods of making the same. The articles can be single layered or multilayered. The single layered articles possess desirable antistatic properties and desirable properties of comfort and feel. The multilayered articles have an outermost layer/surface that possesses desirable antistatic properties and an innermost layer/surface that exhibits desirable properties of comfort and feel. In preferred embodiments, the elastomeric articles are made form a nitrile/natural rubber blend. Articles of the present invention have antistatic properties measured as having a surface resistivity below about 1014 Ω/sq and a static decay time of less than about 60 seconds.
