    摘要: 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.

    摘要: A process for producing agglomerates with a core/shell structure, in which i) initial agglomerates containing a first particulate solid are prepared; ii) a second particulate solid is agglomerated in the presence of the initial agglomerates with the addition of a binder liquid to give second stage agglomerates and, where appropriate, iii) an nth (n≧3) solid is agglomerated in the presence of the (n−1)th stage agglomerates with the addition of a binder liquid to give nth stage agglomerates.
