  • Polar monomer containing copolymers derived from olefins useful as lubricant and fuel oil additives, processes for preparation of such copolymers and additives and use thereof
    Patent number: 6172015
    Abstract: Polar monomer-containing copolymers derived from at least one &agr;, &bgr; unsaturated carbonyl compound, such as alkyl acrylates and one or more olefins, such olefins including ethylene and C3-C20 &agr;-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.

  • Polymers derived from olefins useful as lubricant and fuel oil additives, processes for preparation of such polymers and additives and use thereof
    Patent number: 6017859
    Abstract: Polymers (including copolymers) derived from one or more olefins, such including ethylene and C.sub.3 -C.sub.20 .alpha.-olefins such as propylene and 1-butene, which polymers 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 polymer chains comprising the polymer; (c) at least about 50% of said branches being methyl and/or ethyl branches; (d) at least about 30% of said polymer chains terminated with a vinyl or vinylene group; (e) a number average molecular weight, Mn, of from about 300 to about 15,000 when the polymer is intended for dispersant or wax crystal modifier uses and up to about 500,000 where intended for viscosity modifier uses; and (f) substantial solubility in hydrocarbon and/or synthetic base oil.
