  • Patent number: 6878683
    Abstract: Polymers of a poly(meth)acrylic acid main chain in which, based on the main chain, 0 to 30% by weight of the (meth)acrylic acid basic building blocks may be replaced by maleic acid (anhydride) basic building blocks, fumaric acid basic building blocks or mixtures thereof and 0 to 10% by weight of the (meth)acrylic acid basic building blocks may be replaced by other copolymerizable ethylenic basic building blocks, and C1-30-alkylpoly-C2-4-alkylene glycols, bonded to the main chain via ester groups, having an average molecular weight of from 250 to 10 000 as side chains, where, based on the polymer, 1 to 19% by weight of the main chain and 81 to 99% by weight of the side chains are present and this ratio and the average molecular weight of the side chains are chosen such that free carboxyl groups are present in the polymer, are used as controllable dispersants for detergents or cleaners or constituents thereof.

  • Patent number: 6486279
    Abstract: Activation of ruthenium based catalyst compounds with acid to improve reaction rates and yields of olefin metathesis reactions, including ROMP, RCM, ADMET and cross-methasis reactions is disclosed. The ruthenium catalyst compounds are ruthenium carbene complexes of the general formula AxLyXzRu═CHR′ where x=0, 1 or 2, y=0, 1 or 2, and z=1 or 2 and where R′ is hydrogen or a substituted or unsubstituted alkyl or aryl, L is any neutral electron donor, X is any anionic ligand, and A is a ligand having a covalent structure connecting a neutral electron donor and an anionic ligand. The use of acid with these catalysts allows for reactions with a wide range of olefins in a variety of solvents, including acid-initiated RIM processes and living ROMP reactions of water-soluble monomers in water.
