Abstract
The present invention provides a polymeric material containing conductivity control agents derived from a hydroxyalkylphosphonium sulfonate salt. The conductivity control agents can be used with semi-conductive rolls, belts and other biasable members. The inclusion of the conductivity control agent in polymeric or polyurethane elastomers extends the electrical life of the polymer biasable member in low humidity environments. Additionally, the resistivity of the elastomeric polyurethane or polymer on the biasable member is controlled to a desirable value by adjusting the conductivity control agent level in the elastomers.
