Abstract
This invention relates to compositions comprising (1) acrylic-type ester-acrylonitrile copolymers and (2) polymeric polyamines; and to such compositions in combination with organic liquids such as hydrocarbon fluids in which such compositions are effective as antistatic agents.
Claims12
A hydrocarbon fuel containing an effective antistatic amount of composition comprising
- (1) a copolymer of (a) a monomer of the formula ##STR24## and (b) a monomer of the formula ##STR25## Where R' and R", which may be the same or different, are hydrogen or an alkyl group and R is selected from the group consisting of alkyl, cycloalkyl, aryl and alkaryl, the molar ratio of (b) to (a) being from about 10:1 to 1:10, and the molecular weight of the copolymer being at least about 1000;
- and
- (2) a polymeric polyamine selected from the group consisting of (i) the reaction product of an epihalohydrin and an amine and (ii) an .alpha.-olefin-maleimide copolymer.
