ABSTRACT:
This invention relates to copolymers of alpha-olefins and maleic anhydride reacted with amines in the presence of Lewis acids, preferably BF.sub.3 or a complex thereof; and to the use of these products as anti-static agents in organic liquids, preferably in hydrocarbons. The use of Lewis acid produces a unique reaction product which is superior as to fluidity and/or anti-static properties as compared to the corresponding product produced without Lewis acid. In addition, the use of Lewis acid promotes the rate of reaction thus reducing reaction time.
