Abstract
Ethylene and an olefinically unsaturated aliphatic monomer containing 3 to 5 carbon atoms in the molecule are copolymerized by reacting the two component monomers at high temperature and pressure in the presence of a solvent, a catalyst, and a small quantity of either carbon tetrachloride or a mercaptan to produce a copolymer having a molecular weight of 1000 to 3000. The preferred monomer is vinyl acetate although vinyl propionate, methyl methacrylate, allyl ethyl ether, divinyl ether, acrylonitrile and vinyl acetonitrile are also specified. The solvent is preferably benzene and the catalyst di-t.-butyl peroxide. The exemplified mercaptan is dodecyl mercaptan. The ingredients of the reaction mixture are preferably added continuously. The resulting copolymers are pour-point depressants for fuel oils.ALSO:A pour-point depressant for fuel oils comprises a copolymer of ethylene and an olefinically unsaturated aliphatic monomer having 3-5 carbon atoms per molecule, said copolymer having a molecular weight of 1,000 to 3,000 and having been made by solution polymerizing the two monomers at high temperatures and pressures in the presence of a catalyst and a small proportion of carbon tetrachloride or a mercaptan. The unsaturated monomer may be vinyl acetate or propionate, methyl methacrylate, allyl ethyl ether, divinyl ether, acrylonitrile, or vinylacetonitrile. Fuels oils mentioned include aviation turbo-jet fuels, kerosene, heating oils, Nos. 1 and 2 fuel oils, diesel fuels and gas oils.
