    Abstract: Copolymer (A), obtained by polymerizing olefin monomers (M), is new. Copolymer (A) obtained by polymerizing olefin monomers (M) of formulae ((R1>-C=) (M1); (R2>)(R3>)C=C(R4>)(R5>) (M2); and (R7>)(R6>)C=C(R8>)(R9>) (M3)), is new. R1>H or 1-40C-hydrocarbyl; R2>-R5>H, 1-40C-hydrocarbyl, COOR1>0> or OCOR1>0> (where at least one of R2>-R5 is COOR1>0> or OCOR1>0>); R6>-R8>H or 1-4C-alkyl; R9>aryl; and R1>0>1-40C-hydrocarbyl. Independent claims are included for: (1) a fuel oil composition comprising a larger amount of a distillate fuel with a boiling point of 120-500[deg]C and smaller amount of at least a copolymer; (2) a lubricant composition comprising a larger amount of a conventional lubricant and smaller amount of at least a copolymer; and (3) an additive package comprising at least a copolymer in combination with at least a conventional grease additive or a fuel oil additive.

    Abstract: Water-soluble copolymers which comprise, in copolymerized form, (a) 60 to 99% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I H2C═CR1—X—YR2—OnR3  I  in which the variables have the following meanings: X is —CH2— or —C(O)—, if Y is —O—; is —C(O)—, if Y is —NH—; is —O— or —O—(CH2)4—, if Y is a chemical bond; Y is —O—, —NH— or a chemical bond; R1 is hydrogen or methyl; R2 is C2-C4-alkylene radicals, which may be identical or different and also linear or branched, but where at least 50% of the radicals R2 are ethylene; R3 is C1-C22-alkyl, phenyl, p-(C1-C12-alkyl)phenyl or hydrogen; n is an integer from 6 to 50, (b) 1 to 40% by weight of at least one nonquaternized dipolar monomer comprising at least one nitrogen atom, (c) 0 to 39% by weight of other nonionic monoethylenically unsaturated monomers and (d) 0 to 10% by weight of other anionic monoethylenically unsaturated monomers and have an average molecular weight Mw of from 2000 to 500 000 D, and the use of the copolymers as dispersants and sequestrants for pigmented materials, as additive for detergents, laundry pretreatment compositions, cleaners for hard surfaces, dentifrices and bodycare compositions, and as auxiliaries for textile processes, paper making and paper processing and deinking processes.

    Abstract: The synthesis of dolastatin 3, which inhibits cell growth, requires a 2-aminomethyl-thiazol-4-carboxylic acid that is protected on the amino group as a building block. The invention provides a synthesis for producing this compound with a high degree of purity and a high yield so that it is also feasible on an industrial scale. To this end, a glycine thioamide with a protective group on the amino group is reacted preferably with 3-brom-2-oxo-propionic acid in the presence of at least one tertiary amine.
