LIQUID PETROLEUM HYDROCARBON COMPOSITIONS CONTAINING ESTERS OF AN ALKYL ITACONATE-MALEIC ANHYDRIDE COPOLYMER AS FLUIDITY IMPROVERS

摘要

Liquid petroleum hydrocarbon compositions are provided which contain small amounts, sufficient to improve their fluidity characteristics, of an ester of an alkyl itaconate-maleic anhydride copolymer. A method for preparing these ester copolymers is also provided.
