Abstract
Quaternary ammonium salt antistatic agents having an organic chain of ten to twenty-five atoms plasticize the vinyl resin of a static charge dissipative surface covering. Such antistatic agents minimize migration and therefore retain their charge dissipative properties for a longer period of time. The class of plasticizing quaternary ammonium salt antistatic agents includes derivatives of unsaturated organic acids and alkyl ethers having a chain length of six to eighteen carbon atoms and a hydroxyl functionality.
