Abstract
Disclosed is a composition for dissipating an electrostatic charge in a polymer matrix. The composition includes an oxirane copolymer wherein said copolymer is prepared from ethylene oxide and either a heterocyclic monomer or a vinyl type monomer. The polymer matrix is either a plastic or an elastomer. In a further embodiment, a third constituent of non ESD polymer or non ESD filler is utilized in the composition to further enhance the electrostatic dissipating performance, and optionally also toughness of the composition.
