Abstract:
An oil composition includes an oil and an effective amount of a wax inhibitor that includes at least one modified alpha-olefin maleic anhydride copolymer of the formula: wherein R1 is selected from hydrogen or hydrocarbyl groups containing 12-60 carbon atoms and an average carbon atom number of R1, if not hydrogen, in the copolymer is in a range from 20 to 32, R2 is selected from hydrocarbyl groups containing 6-12 carbon atoms, and n is a number of repeating units ranging from 1 to 100.
