Abstract:
A composition having increased electrical conductivity, comprising a liquid hydrocarbon and an anti-static amount of a hydrocarbon soluble copolymer of an alkylvinyl monomer and a cationic vinyl monomer. The copolymer has an alkylvinyl monomer unit to cationic vinyl monomer unit ratio of from about 1:1 to about 10:1, and has an average molecular weight of from about 800 to about 1,000,000. Other related compositions and methods for measuring electrical conductivity of liquids are also disclosed.
