POLYOLEFIN GRAFTED WITH POLYMERS OF NITROGEN CONTAINING MONOMERS AND LUBRICANTS AND FUEL COMPOSITIONS CONTAINING SAME

Abstract of the Disclosure This invention relates to a method for preparing graft copolymers having 2-vinylpyridine branches (or other nitrogen-containing branches) on a backnone consisting of an ethylene/propylene copolymer or an ethylene/propylene/diene terpolymer or other polyolefinic backbone. These graft copolymers are soluble in oil, whether of mineral (petroleum) origin or of synthetic nature, and impart thereto improved properties. This invention further relates to lubricating oil compositions and hydrocarbon fuel compositions containing the graft copolymers. They impart several beneficial properties to these fluids, in particular improvements in disper-sancy but also enhanced viscosity and viscosity/temperature relation-ships. The graft copolymers, when added to the oil, yield lubricants which are excellent dispersants for sludge formed in spark ignition and compression ignition engines.

Improved stabilising additives for distillate fuels

Petroleum distillate fuels boiling between 300 DEG and 900 DEG F. are stabilized by the addition of a copolymer of the reaction product of epichlorhydrin and an unsaturated polymerizable compound containing a carboxyl group with a vinyl or vinylidene monomer or mixture thereof with another comonomer (see Group IV (a)). The epichlorhydrin reaction product is preferably a mixed ester of a dibasic acid of the formula <FORM:0836323/III/1> where R is a C8-C24 alkyl group, R1 and R11 are hydrogen or methyl and n is 1-3. Suitable comonomers are styrene, isobutylene, butadiene, allyl acetate, vinyl propionate, methyl methacrylate, allyl ethyl ether, divinyl ether, acrylonitrile or vinyl acetonitrile with which may be mixed lauryl maleate or tallow fumarate. The copolymer preferably has a molecular weight of 3,000-100,000 and is added in amounts of 0.002-2% by weight to heating oils, diesel fuels or jet engine fuels.ALSO:Mixed esters of unsaturated dibasic acids having the formula ROCOCR1=CR11COO(CH2CH(CH2Cl)O)nH where R is preferably a C8-C24 alkyl group, R1 and R11 are hydrogen or methyl, at least one preferably being hydrogen, and n is 1 to 3 are prepared by reacting a long chain alkyl half ester of the acid with epichlorhydrin. The acid may be maleic, fumaric, citraconic or mesaconic and the long chain alkyl group derived from straight or branched chain alcohols or mixtures thereof such as dodecyl, cetyl, eicosyl, docosyl, 2 - ethylhexanol - 1, C8 oxo - alcohols, capryl alcohol or the product obtained by hydrogenation of coconut oil (sold under the name "Lorol"). The ester: epichlorhydrin mol. ratio may be 1:1 to 1:4 but is preferably 1:1. They are reacted in the presence of 0.05 to 5% by weight of BF3 or its etherate, AlCl3 or AlBr3 or a basic catalyst such as NaOCH3 or NaOH. The temperature may be 100-180 DEG C. and the epichlorhydrin is preferably added to the half ester over 1-2 hours and then reacted for 4-24 hours. A solvent such as benzene, toluene ...
