Abstract: A thermoplastic composition comprises (A) 100 parts by weight of a thermoplastic polymer, such as polycarbonate or a blend thereof, (B) 0.0001-10 parts by weight of a sulfonic acid phosphonium salt as an antistatic agent, and (C) 0.01-1 parts by weight of a silicone oil based compound as an antistatic activity enhancer. Such a composition shows a good antistatic behavior without compromising optical properties. Optionally an antistatic synergist may be present.
