  • Method of making poly (linseed oil/isobutyl methacrylate) as a coagulant for oil
    Patent number: 5698139
    Abstract: The invention discloses methods of making oil coagulant compositions, the oil coagulants made thereby and processes for using the coagulants to coagulate oil that has been spilled on water. The coagulant comprises a glyceride, such as, for example, the drying oil linseed oil, a polymer, such as, for example, poly(isobutyl methacrylate), and a solvent, such as, for example, 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate. The coagulant of the present invention coagulates oil independent of both agitation and temperature, and may be used in both salt and fresh water. After the coagulant has coagulated the spilled oil, the coagulated oil may be readily mechanically removed from the water such that at least 99.9% of the oil is removed from the water and only a faint trace of oil remains in the water.
