Abstract
The invention relates to the use of a gel-like polymer composition, which is produced by means of a radical polymerization of an [alpha],[beta]-ethylenically unsaturated acid in the presence of at least one polyether component, in formulations for automatic dishwashing (ADW).
Claims36
A machine dishwashing formulation which comprises a polymer composition in gel form, obtainable by a process in which
- a) Providing a monomer composition M) consisting of
- A) at least one α,β-ethylenically unsaturated acid, and
- B) 0% to 0.1% by weight, based on the total weight of the monomer composition M), of crosslinking monomers having two or more than two polymerizable α,β-ethylenically unsaturated double bonds per molecule,
- b) Subjecting the monomer composition M) provided in step a) to a free-radical polymerization in the presence of at least one polyether component PE) selected from polyetherols having a number-average molecular weight of at least 200 g/mol and the mono- and di-(C1-C6-alkyl ethers) thereof, surfactants containing polyether groups and mixtures thereof.
