International ClassesC08F 004/649C08F 212/36 C08F 230/08 AbstractFluid flow friction loss of a hydrocarbon liquid is improved by adding a small amount of a copolymer of divinylbenzene and a linear alpha-olefin or a copolymer of vinyl siloxane and a linear alpha-olefin to the liquid hydrocarbon. A preferred catalyst for producing these materials is also described.Field of SearchSilicon present in organic non-metal compound | |
