摘要：
Electret webs are presented which include a blend of a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additives include a heterocyclic imide material which is free of fluorinated groups. The webs prepared from the blends may be in the form of films or non-woven fibrous webs. Non-woven microfiber webs are useful as filtration media.
