Abstract: Polar monomer-containing copolymers derived from at least one .alpha., .beta. unsaturated carbonyl compound, such as alkyl acrylates and one or more olefins, such olefins including ethylene and C3-C20 .alpha.-olefins such as propylene and 1-butene, which copolymers have (a) an average ethylene sequence length, ESL, of from about 1.0 to less than about 3.0; (b) an average of at least 5 branches per 100 carbon atoms of the copolymer chains comprising the copolymer; (c) at least about 50 % of said branches being methyl and/or ethyl branches; (d) substantially all of said incorporated polar monomer is present at the terminal position of said branches; (e) at least about 30 % of said copolymer chains terminated with a vinyl or vinylene group; (f) a number average molecular weight, Mn, of from about 300 to about 15,000 when the copolymer is intended for dispersant or wax crystal modifier uses and up to about 500,000 where intended for viscosity modifier uses; and (g) substantial solubility in hydrocarbon and/or synthetic base oil. The copolymers are produced using late-transition-metal catalyst systems and, as an olefin monomer source other than ethylene preferably inexpensive, highly dilute refinery or steam cracker feed streams that have undergone only limited cleanup steps. Fuel and lubricating oil additives, particularly dispersants, wax crystal modifiers and flow improvers, are produced. Where functionalization and derivatization of these copolymers are required for such additives it is facilitated by the olefinic structures available in the copolymer chains.

Abstract: The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene/alpha-olefin/diene interpolymer of 300 to 20,000 number average molecular weight substituted with mono- or dicarboxylic acid producing moieties (preferably dicarboxylic acid or anhydride moieties), wherein the terminal unsaturation comprises terminal ethenylidene unsaturation. The mono- and dicarboxylic acid or anhydride substituted interpolymers of this invention are useful per se as additives to lubricating oils, and can also be reacted with a nucleophilic reagent, such as amines, alcohols, amino alcohols and reactive metal compounds, to form products which are also useful lubricating oil additives, e.g., as dispersants.

Abstract: An improved process for the copolymerization of ethylene and alpha -olefins utilizing highly dilute alpha -olefin feedstreams to effect high conversions and catalyst productivities. The instant invention is particularly adaptable to copolymerizing the alpha -olefin content of commercially available refinery feedstreams such as Raffinate-2.
